180-x=180-4x+30
Combine -5x and 4x to get -x.
180-x=210-4x
Add 180 and 30 to get 210.
180-x+4x=210
Add 4x to both sides.
180+3x=210
Combine -x and 4x to get 3x.
3x=210-180
Subtract 180 from both sides.
3x=30
Subtract 180 from 210 to get 30.
x=\frac{30}{3}
Divide both sides by 3.
x=10
Divide 30 by 3 to get 10.
