4x+8x-4=4-2\left(4x+24\right)
Use the distributive property to multiply -4 by -2x+1.
12x-4=4-2\left(4x+24\right)
Combine 4x and 8x to get 12x.
12x-4=4-8x-48
Use the distributive property to multiply -2 by 4x+24.
12x-4=-44-8x
Subtract 48 from 4 to get -44.
12x-4+8x=-44
Add 8x to both sides.
20x-4=-44
Combine 12x and 8x to get 20x.
20x=-44+4
Add 4 to both sides.
20x=-40
Add -44 and 4 to get -40.
x=\frac{-40}{20}
Divide both sides by 20.
x=-2
Divide -40 by 20 to get -2.
