-4-2\times 2-4x+40=-80
Multiply both sides of the equation by 8, the least common multiple of 8,4,2.
-4-4-4x+40=-80
Multiply -2 and 2 to get -4.
-8-4x+40=-80
Subtract 4 from -4 to get -8.
32-4x=-80
Add -8 and 40 to get 32.
-4x=-80-32
Subtract 32 from both sides.
-4x=-112
Subtract 32 from -80 to get -112.
x=\frac{-112}{-4}
Divide both sides by -4.
x=28
Divide -112 by -4 to get 28.
