-4x=-2-2y
Subtract 2y from both sides.
-4x=-2y-2
The equation is in standard form.
\frac{-4x}{-4}=\frac{-2y-2}{-4}
Divide both sides by -4.
x=\frac{-2y-2}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{y+1}{2}
Divide -2-2y by -4.
2y=-2+4x
Add 4x to both sides.
2y=4x-2
The equation is in standard form.
\frac{2y}{2}=\frac{4x-2}{2}
Divide both sides by 2.
y=\frac{4x-2}{2}
Dividing by 2 undoes the multiplication by 2.
y=2x-1
Divide -2+4x by 2.
