Exercise 2 Page 270

Use the Multiplication Property of Equality to eliminate the division.

x=40

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Multiplication Property of Equality, we will multiply both sides of the equation by 8. This will eliminate the denominator of the fraction and isolate x.

x/8=5

LHS * 8=RHS* 8

x/8* 8=5* 8

a/8* 8 = a

x=5* 8

Multiply

x=40
