Exercise 60 Page 422

Use the Subtraction Property of Equality to eliminate the addition.

x=74

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 16 from both sides of the equation. This will eliminate the addition and isolate x.

16+x=90

LHS-16=RHS-16

16+x-16=90-16

Subtract terms

x=74
