30+8x+420-12x=370
Use the distributive property to multiply 12 by 35-x.
450+8x-12x=370
Add 30 and 420 to get 450.
450-4x=370
Combine 8x and -12x to get -4x.
-4x=370-450
Subtract 450 from both sides.
-4x=-80
Subtract 450 from 370 to get -80.
x=\frac{-80}{-4}
Divide both sides by -4.
x=20
Divide -80 by -4 to get 20.
