Exercise 6 Page 251

Use the Division Property of Equality to eliminate the multiplication.

x=6.5

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 14. This will eliminate the multiplication and isolate x.

14x = 91

.LHS /14.=.RHS /14.

14x/14 = 91/14

CancelCommonFac

Cancel out common factors

14x/14 = 91/14

Simplify quotient

x = 91/14

a/b=.a /7./.b /7.

x = 13/2

Calculate quotient

x = 6.5
