Exercise 36 Page 91

Construct a two-column table. On the left column state the steps and on the right column the reason of each step.

-6

Practice makes perfect

To solve the equation, we will construct a two-column table. On the left column we will state the steps and on the right column the reason of each step. Let's start by using the Subtraction Property of Equality and subtract 3 from both sides. Then, we will use the Multiplication Property of Equality and multiply both sides by - 2.

Steps	Reasons
3-x/2=6	Original equation
3-x/2 - 3=6 - 3	Subtraction Property of Equality
- x/2=3	Use subtraction to simplify.
- 2(- x/2)= - 2(3)	Multiplication Property of Equality
x=- 6	Use multiplication to simplify.
