6x-50+40+4x-90=180
Combine 3x and 3x to get 6x.
6x-10+4x-90=180
Add -50 and 40 to get -10.
10x-10-90=180
Combine 6x and 4x to get 10x.
10x-100=180
Subtract 90 from -10 to get -100.
10x=180+100
Add 100 to both sides.
10x=280
Add 180 and 100 to get 280.
x=\frac{280}{10}
Divide both sides by 10.
x=28
Divide 280 by 10 to get 28.
