2m=8-4x
Subtract 4x from both sides.
\frac{2m}{2}=\frac{8-4x}{2}
Divide both sides by 2.
m=\frac{8-4x}{2}
Dividing by 2 undoes the multiplication by 2.
m=4-2x
Divide 8-4x by 2.
4x=8-2m
Subtract 2m from both sides.
\frac{4x}{4}=\frac{8-2m}{4}
Divide both sides by 4.
x=\frac{8-2m}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{m}{2}+2
Divide 8-2m by 4.
