-2x=6-2y
Subtract 2y from both sides.
\frac{-2x}{-2}=\frac{6-2y}{-2}
Divide both sides by -2.
x=\frac{6-2y}{-2}
Dividing by -2 undoes the multiplication by -2.
x=y-3
Divide 6-2y by -2.
2y=6+2x
Add 2x to both sides.
2y=2x+6
The equation is in standard form.
\frac{2y}{2}=\frac{2x+6}{2}
Divide both sides by 2.
y=\frac{2x+6}{2}
Dividing by 2 undoes the multiplication by 2.
y=x+3
Divide 6+2x by 2.
