Exercise 6 Page 153

Start by using the Subtraction Property of Equality.

- 7

Practice makes perfect
To solve the equation, we have to isolate x on one side. We will begin by subtracting 5 from both sides. This is allowed by the Subtraction Property of Equality.
x+5=- 2
x+5-5=- 2-5
x=- 7
Therefore, x=- 7 is the solution to the equation. To check that we have the correct solution, we can substitute x=- 7 into the original equation and simplify.
x+5=- 2
- 7+5? =- 2
- 2=- 2
Since the left-hand side and the right-hand side are equal, x=- 7 is a correct solution.
