A. Review1. To solve an equation, you try to isolate the
variable.2. Addition and subtraction are inverse operations
that can be used to isolate a variable.

B. Multiplication and Division are also Inverse Operations1. They can be used to isolate a variable by
a. Multiplying each side by the same number (to get rid of division)
Example: = 2
b. Dividing each side by the same number (to get rid of
multiplication)Example: 5x = 25
c. Multiplying each side by the reciprocal ( do get rid of a
fraction)Example: 12 = x
