The document provides an overview of lessons on linear equations for a math class over 3 days. Key points covered include:
- Day 1 focuses on defining linear equations, properties of equality, and solving linear and rational equations.
- Day 2 covers solving equations involving radicals, absolute values, and literal equations.
- Day 3 involves word problems including number, geometry, digit, investment, age, mixture, uniform motion, work, and clock problems, which are modeled and solved using linear equations.

Students also learn to graph linear equations using x and y intercepts.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
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.

4. An equation is a statement that two mathematical expressions are equivalent or equal. DEFINITION EQUATION The values of the unknown that makes the equation true are called solutions or roots of the equation, and the process of finding the solution is called solving the equation. Example: Week 1 Day 1
13. DEFINITION LINEAR EQUATION IN ONE VARIABLE A linear equation in one variable is an equation that can be written in the form a x + b = 0 where a and b are real numbers and a 0 Example: 2 x – 1 = 0, -5 x = 10 + x , 3 x + 8 = 2 Week 1 Day 2
14. Nonlinear; contains the square of the variable Nonlinear; contains the reciprocal of the variable Nonlinear; contains the square root of the variable Week 1 Day 2 Linear Equations Nonlinear Equations
15. SOLVING A LINEAR EQUATION IN ONE VARIABLE Steps 1. Simplify the algebraic expressions on both sides of the equation. 2. Gather all the variable terms on one side of the equation and all constant terms on the other side. 3. Isolate the variable. 4. Check the solution by substituting the value of the unknown into the original equation. Week 1 Day 2
16. EXAMPLE Problem #23 on page 97 Week 1 Day 2 Solve for the indicated variable: 2(x-1)+3=x-3(x+1) STEP DESCRIPTION EXAMPLE 1 Simplify the algebraic expression on both sides 2(x-1)+3 = x-3(x+1) 2x-2+3 = x-3x-3 2x+1 = -2x-3 2 Gather all the variables on one side of the equation and all constant terms on the other side. 2x+2x = -3-1 4x = -4 3 Isolate the variable
19. SOLVING RATIONAL EQUATIONS THAT ARE REDUCIBLE TO LINEAR EQUATIONS A rational equation is an equation that contains one or more rational expressions. Extraneous solution are solutions that satisfy a transformed equation but do not satisfy the original equation. Steps 1. Determine any excluded values(denominator equals 0). 2. Multiply the equation by the LCD. 3. Solve the resulting linear equation. 4. Eliminate any extraneous solution. Week 1 Day 2
26. Solve each equations: (examples on page 131) Solve each equations: EXAMPLE Week 1 Day 3
27. SOLVING FOR ONE VARIABLE IN TERMS OF THE OTHER Many formulas in the sciences involve several variables, and it is often necessary to express one of the variables in terms of the others. Week 1 Day 3
