assume you meant -12/w = -15 / (w - 1)
cross multiply
-15w = -12(w - 1)
distribute
-15w = -12w + 12
add 12w for both sides
-3w = 12
divide -3 for both sides
w = -4
w can not be 0 or 1

-12/w=-15/(w-1)
Cross Multiply getting:
-15w = -12(w-1) = -12w +12
-3w = 12
w = -4

-12w + 12 = -15w
12 = -3w
w = -4

Hi,
-12.....-15
-----.=.------
.w........w-1
Cross multiply.
-12(w - 1) = -15w
-12w + 12 = -15w
12 = -3w
-4 = w
I hope that helps!! :-)

(15-12)/w = -1
3/w = -1
w = -3
