6=6-15+15w-10w
Use the distributive property to multiply -3 by 5-5w.
6=-9+15w-10w
Subtract 15 from 6 to get -9.
6=-9+5w
Combine 15w and -10w to get 5w.
-9+5w=6
Swap sides so that all variable terms are on the left hand side.
5w=6+9
Add 9 to both sides.
5w=15
Add 6 and 9 to get 15.
w=\frac{15}{5}
Divide both sides by 5.
w=3
Divide 15 by 5 to get 3.
