Exercise 70 Page 10

Use the Subtraction Property of Equality to eliminate the addition.

x=-16

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 36 from both sides of the equation. This will eliminate the addition and isolate x.

36+x=20
SubEqn

LHS-36=RHS-36

36+x-36=20-36
