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