Question

Which of the following operations would be used to solve y−7=38?

- 7
×−7
+ 7
-266

Answer 1

Answer: add 7

Step-by-step explanation: To solve for y, we need to isolate y and we do that by using inverse operations.

Since we have -7 on the left side, the opposite of subtracting is adding.

So we add 7 to both sides to get y = 45.

Answer 2

Add 7 to each side

Explanation:

y−7=38

Add 7 to each side

y−7+7=38+7

y = 45
