Question

What should be done to both sides of the equation in order to solve w - 9 = 15? Add 15. Subtract 15. Add 9. Subtract 9.

Answer 1

Add 9
`(1)/(2)`.

Explanation:

In w - 9 = 15, we have to do inverse opporation, so we must add instead of subtracting.

Hope this helped!

Answer 2

that would be add 9:-

w - 9 + 9 = 14 + 9

w + 0 = 23

w = 23
