Exercise 59 Page 422

Use the Subtraction Property of Equality to eliminate the addition.

x=32

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 58 from both sides of the equation. This will eliminate the addition and isolate x.

x+58=90

LHS-58=RHS-58

x+58-58=90-58

Subtract terms

x=32
