Exercise 69 Page 10

Use the Subtraction Property of Equality to eliminate the addition.

x=25

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 18 from both sides of the equation. This will eliminate the addition and isolate x.

18+x=43
SubEqn

LHS-18=RHS-18

18+x-18=43-18
