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