4x=4-2y
Subtract 2y from both sides.
\frac{4x}{4}=\frac{4-2y}{4}
Divide both sides by 4.
x=\frac{4-2y}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{y}{2}+1
Divide 4-2y by 4.
2y=4-4x
Subtract 4x from both sides.
\frac{2y}{2}=\frac{4-4x}{2}
Divide both sides by 2.
y=\frac{4-4x}{2}
Dividing by 2 undoes the multiplication by 2.
y=2-2x
Divide 4-4x by 2.
