Question 2

LINEAR EQUATIONS AND INEQUALITIES

Question 3

Consider the two equations:

Question 4

x- 6 = 3 and x= 9

Question 5

Both equations have 9 as a solution

Answer 5

and both can be solved by inspection. However

Question 6

easier to recognize 9 as a solution to the second equation. Two equations which have exactly

Question 7

the same solution are called equivalent equations.

Question 8

We apply the following properties of equality to solve linear equations in one variable.

Question 9

Addition - Subtraction Property

Question 10

If the same number or expression is added to or subtracted from both

Question 11

sides of an equation

Answer 11

the resulting equation is equivalent (or has the same

Question 12

solutions as) to the original.

Question 13

Multiplication-Division Property

Question 14

If each side of an equation is multiplied or divided by the same non-zero

Question 15

number or expression

Answer 15

the resulting equation is equivalent (or has the

Question 16

same solutions as) to the original.
