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