solving linear equation in one variable by applying the properties of equalities

2. They are also called first-degree
equation in the form ax + by=c..
are equations in one or more than one
variables, where the variable has
exponents equal to one.

3. is an equation of first-
degree in one variable, it
can be solve using real
numbers and equality of
property.

5. Example:
x - 4 = 3
x – 4 + 4 = 3 + 4
x + 0 = 7
x = 7
add 4 both sides

6. B. Subtraction property
of equality
x + 2 = 5
Example:
x + 2 – 2 = 5 – 2
x + 0 = 7
x + 2 = 5
subtract 2 both sides

7. C. multiplication property of
equality
Example:
x / 11 = 4
11 ◦ x / 11 = 4 ◦ 11
X = 44
multiply 11 both
sides

8. D. Division property of
equality
Example:
4x = 20
4x / 4 = 20 / 4
x = 5
divide 4 both sides
