-27=-7w+5w-15
Use the distributive property to multiply 5 by w-3.
-27=-2w-15
Combine -7w and 5w to get -2w.
-2w-15=-27
Swap sides so that all variable terms are on the left hand side.
-2w=-27+15
Add 15 to both sides.
-2w=-12
Add -27 and 15 to get -12.
w=\frac{-12}{-2}
Divide both sides by -2.
w=6
Divide -12 by -2 to get 6.
