y=3-3x
Combine -2x and -x to get -3x.
3-3x=y
Swap sides so that all variable terms are on the left hand side.
-3x=y-3
Subtract 3 from both sides.
\frac{-3x}{-3}=\frac{y-3}{-3}
Divide both sides by -3.
x=\frac{y-3}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-\frac{y}{3}+1
Divide y-3 by -3.
y=3-3x
Combine -2x and -x to get -3x.
