180=2x+x+30
Combine x and x to get 2x.
180=3x+30
Combine 2x and x to get 3x.
3x+30=180
Swap sides so that all variable terms are on the left hand side.
3x=180-30
Subtract 30 from both sides.
3x=150
Subtract 30 from 180 to get 150.
x=\frac{150}{3}
Divide both sides by 3.
x=50
Divide 150 by 3 to get 50.
