-4m+80=36
Square both sides of the equation.
-4m+80-80=36-80
Subtract 80 from both sides of the equation.
-4m=36-80
Subtracting 80 from itself leaves 0.
-4m=-44
Subtract 80 from 36.
\frac{-4m}{-4}=-\frac{44}{-4}
Divide both sides by -4.
m=-\frac{44}{-4}
Dividing by -4 undoes the multiplication by -4.
m=11
Divide -44 by -4.
