The document provides information about solving linear equations and systems of linear equations. It defines a linear equation as an equation that can be written in the form ax + by + c = 0, where a, b, and c are real numbers and a and b are not equal to 0. It discusses three methods for solving a pair of linear equations:
1) The graphical method involves plotting the equations on a graph and finding their point of intersection.
2) The algebraic methods include substitution, elimination, and cross-multiplication. Substitution involves solving one equation for one variable and substituting it into the other equation. Elimination involves eliminating one variable to obtain an equation with just one variable.
3) Cross-

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Linear Equations
Definition of a Linear Equation
A linear equation in two variable x is an equation
that can be written in the form ax + by + c = 0,
where a ,b and c are real numbers and a and b is
not equal to 0.
An example of a linear equation in x is 2x – 3y + 4 = 0.
3. A pair of linear equations
in two variables can be
solved by the:
(i) Graphically method
(ii) Algebraic method
4. GRAPHICAL SOLUTIONS OF A
LINEAR EQUATION
Let us consider the following system of
two simultaneous linear equations in
two variable.
2x – y = -1
3x + 2y = 9
Here we assign any value to one of the
two variables and then determine the
value of the other variable from the
given equation.
7. Types of Solutions of Systems of
Equations
• One solution – the lines cross at one point
• No solution – the lines do not cross
• Infinitely many solutions – the lines coincide
9. To solve a pair of linear equations in
two variables algebraically, we have
following methods:(i) Substitution method
(ii) Elimination method
(iii) Cross-multiplication
method
10. SUBSTITUTION METHOD
STEPS
Obtain the two equations. Let the equations be
a1x + b1y + c1 = 0 ----------- (i)
a2x + b2y + c2 = 0 ----------- (ii)
Choose either of the two equations, say (i) and
find the value of one variable , say ‘y’ in terms
of x
Substitute the value of y, obtained in the
previous step in equation (ii) to get an equation
in x
11. Solve the equation obtained in the
previous step to get the value of x.
Substitute the value of x and get
the value of y.
Let us take an example
x + 2y = -1 ------------------ (i)
2x – 3y = 12 -----------------(ii)
12. x + 2y = -1
x = -2y -1 ------- (iii)
Substituting the value of x in
equation (ii), we get
2x – 3y = 12
2 ( -2y – 1) – 3y = 12
- 4y – 2 – 3y = 12
- 7y = 14 ; y = -2 ,
13. Putting the value of y in eq. (iii), we get
x = - 2y -1
x = - 2 x (-2) – 1
=4–1
=3
Hence the solution of the equation
is
( 3, - 2 )
14. ELIMINATION METHOD
• In this method, we eliminate one of the
two variables to obtain an equation in one
variable which can easily be solved.
Putting the value of this variable in any of
the given equations, the value of the other
variable can be obtained.
• For example: we want to solve,
3x + 2y = 11
2x + 3y = 4
15. Let 3x + 2y = 11 --------- (i)
2x + 3y = 4 ---------(ii)
Multiply 3 in equation (i) and 2 in equation
(ii) and subtracting eq iv from iii, we get
9x + 6y = 33 ------ (iii)
4x + 6y = 8 ------- (iv)
5x = 25
x=5
16. • putting the value of X in equation (ii) we
get,
2x + 3y = 4
2 x 5 + 3y = 4
10 + 3y = 4
3y = 4 – 10
3y = - 6
y=-2
Hence, x = 5 and y = -2
