12x+20=8x-20
Use the distributive property to multiply 4 by 3x+5.
12x+20-8x=-20
Subtract 8x from both sides.
4x+20=-20
Combine 12x and -8x to get 4x.
4x=-20-20
Subtract 20 from both sides.
4x=-40
Subtract 20 from -20 to get -40.
x=\frac{-40}{4}
Divide both sides by 4.
x=-10
Divide -40 by 4 to get -10.
