2w+30=5w
Multiply both sides of the equation by 10, the least common multiple of 5,2.
2w+30-5w=0
Subtract 5w from both sides.
-3w+30=0
Combine 2w and -5w to get -3w.
-3w=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
w=\frac{-30}{-3}
Divide both sides by -3.
w=10
Divide -30 by -3 to get 10.
