-2x=-3+2y-3
Subtract 3 from both sides.
-2x=-6+2y
Subtract 3 from -3 to get -6.
-2x=2y-6
The equation is in standard form.
\frac{-2x}{-2}=\frac{2y-6}{-2}
Divide both sides by -2.
x=\frac{2y-6}{-2}
Dividing by -2 undoes the multiplication by -2.
x=3-y
Divide -6+2y by -2.
-3+2y=3-2x
Swap sides so that all variable terms are on the left hand side.
2y=3-2x+3
Add 3 to both sides.
2y=6-2x
Add 3 and 3 to get 6.
\frac{2y}{2}=\frac{6-2x}{2}
Divide both sides by 2.
y=\frac{6-2x}{2}
Dividing by 2 undoes the multiplication by 2.
y=3-x
Divide 6-2x by 2.
