2x+2x-90+2x-90=360
Combine x and x to get 2x.
4x-90+2x-90=360
Combine 2x and 2x to get 4x.
6x-90-90=360
Combine 4x and 2x to get 6x.
6x-180=360
Subtract 90 from -90 to get -180.
6x=360+180
Add 180 to both sides.
6x=540
Add 360 and 180 to get 540.
x=\frac{540}{6}
Divide both sides by 6.
x=90
Divide 540 by 6 to get 90.
