Exercise 35 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 20 from both sides. Then, we will use the Division Property of Equality and divide both sides by - 3.

Steps	Reasons
20-3h=2	Original equation
20-3h - 20=2 - 20	Subtraction Property of Equality
- 3h=- 18	Use subtraction to simplify.
- 3h/- 3= - 18/- 3	Division Property of Equality
h=6	Use division to simplify.
