Exercise 20 Page 199

Use the Division Property of Equality to eliminate the multiplication.

x=33

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Division Property of Equality, we will divide both sides of the equation by 3. This will eliminate the multiplication and isolate x.
