B. Subtract 15 from each side.
C. Add 5 to each side.
D. Add 15 to each side.​

Answer 1

C) add 5 to each sides.

Explanation:

1) Add 5 to both sides.

`15 + 5 = y`

2) Simplify 15 + 5 to 20.

`20 = y`

3) Switch sides.

`y = 20`

You need to add 5 to each sides in order to solve this equation. if you do, you'll get an answer of 20.
