Exercise 76 Page 170

Use the Addition Property of Equality to eliminate the subtraction.

Practice makes perfect

To solve the equation, we have to isolate y on one side. Using the Addition Property of Equality, we will add 5 to both sides of the equation. This will eliminate the subtraction on the left-hand side of the equation and isolate y.

y - 5 = 6

AddEqn

LHS+5=RHS+5

y - 5 + 5 = 6 + 5
