4/8y-21=3 What is y?

**Ms. Sue**, Monday, September 23, 2013 at 8:55pmAssuming you copied the problem correctly, your answer is correct.

4/8y-21=3

4/8y = 3 + 21

4/8y = 24

y = 24 / (4/8)

y = 24 * (8/4)

y = 192/4 = 48

Proof:

1/2 (48) - 21 = 3

24 - 21 = 3

**MathMate**, Monday, September 23, 2013 at 8:59pmIf you mean

(4/8)y - 21 = 3

then y=48 as you got.

If the question were

(4/8)y-21=0

then y=42
