Exercise 36 Page 504

Use the Subtraction Property of Equality to eliminate the addition.

Solution: x = - 1
Graph:

Practice makes perfect

To solve the equation, we have to isolate x on one side. Using the Subtraction Property of Equality, we will subtract 2 from both sides of the equation. This will eliminate the addition and isolate x.

x + 2 = 1

LHS-2=RHS-2

x + 2 - 2 = 1 - 2

Subtract terms

x = - 1

Let's mark x = - 1 on the number line.
