2x+30+2x+180-x+x+30+2x=180
Combine x and x to get 2x.
4x+30+180-x+x+30+2x=180
Combine 2x and 2x to get 4x.
4x+210-x+x+30+2x=180
Add 30 and 180 to get 210.
3x+210+x+30+2x=180
Combine 4x and -x to get 3x.
4x+210+30+2x=180
Combine 3x and x to get 4x.
4x+240+2x=180
Add 210 and 30 to get 240.
6x+240=180
Combine 4x and 2x to get 6x.
6x=180-240
Subtract 240 from both sides.
6x=-60
Subtract 240 from 180 to get -60.
x=\frac{-60}{6}
Divide both sides by 6.
x=-10
Divide -60 by 6 to get -10.
