Exercise 38 Page 88

Use the Multiplication Property of Equality to eliminate the division.

Solution: x=35
Property: Multiplication Property of Equality

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 7. This will eliminate the denominator of the fraction and isolate x.

x/7=5

LHS * 7=RHS* 7

x/7* 7=5* 7
