Exercise 18 Page 199

Use the Division Property of Equality to eliminate the multiplication.

s=9

Practice makes perfect

To solve the equation, we have to isolate s on one side. Using the Division Property of Equality, we will divide both sides of the equation by 800. This will eliminate the multiplication and isolate s.

7200=800s

.LHS /800.=.RHS /800.

7200/800=800s/800

Cancel out common factors

7200/800=800s/800

Simplify quotient

7200/800=s

Calculate quotient

9=s

Rearrange equation
