Question
Solve the following equation using the additive property of equality. 12 – y = 7
- 5
- 6
- 7
- 8
The correct answer is: 5
Step 1: Given that
12 – y = 7
Using additive property of equality add y to both sides.
Step 2:
12 – y + y = 7 + y
12 = 7 + y
To isolate the value of y subtract 7 from both sides of the equation.
12 - 7 = 7 + y - 7
So, y = 5
