-5/8w = -9 Help!!!?

multiply both sides by 8:
-5w = -72
then divide both sides by -5:
w = 72/5 or 14.4

hope that helped!

- 5/8w = - 9
w = - 9 * - 8/5
w = 14.4

Answer: w = 14.4

Proof:
- 5/8(14.4) = - 9
- 9 = - 9

(5/8)w = 9
5w = 72
w = 72/5

-5/8 w = -9
-5w/8 = -9
-5w = -72
w = -72/-5
w = 72/5
w = 14.4

-5/8w = -9
Cancel - on both sides
5/8w = 9

Bring 8 to RHS
5w = 9*8
5w = 72
w = 72/5

w = 144/10 = 14.4

Cross multiply and then separate w.
