7x-10-20+3x+4x-30=360
Combine 3x and 4x to get 7x.
7x-30+3x+4x-30=360
Subtract 20 from -10 to get -30.
10x-30+4x-30=360
Combine 7x and 3x to get 10x.
14x-30-30=360
Combine 10x and 4x to get 14x.
14x-60=360
Subtract 30 from -30 to get -60.
14x=360+60
Add 60 to both sides.
14x=420
Add 360 and 60 to get 420.
x=\frac{420}{14}
Divide both sides by 14.
x=30
Divide 420 by 14 to get 30.
