1. Section 3.2 Solving Equations Using Multiplication and Division
Objectives:
Solve linear equations using multiplication and division

2. Remember when you solve a linear equation your goal is to isolate the variable on one side of the equation.
In the last section, you used the fact that addition and subtraction are inverse operations. In this section, you will use the fact that multiplication and division are inverse operations.

3. EX: Solve the equation

4. Addition Property of Equality
Subtraction Property of Equality
Multiplication Property of Equality
Division Property of Equality
The transformations used to isolate the variable in the last two sections are based on rules of algebra called Properties of Equality
