-3x=-9-3y
Subtract 3y from both sides.
-3x=-3y-9
The equation is in standard form.
\frac{-3x}{-3}=\frac{-3y-9}{-3}
Divide both sides by -3.
x=\frac{-3y-9}{-3}
Dividing by -3 undoes the multiplication by -3.
x=y+3
Divide -9-3y by -3.
3y=-9+3x
Add 3x to both sides.
3y=3x-9
The equation is in standard form.
\frac{3y}{3}=\frac{3x-9}{3}
Divide both sides by 3.
y=\frac{3x-9}{3}
Dividing by 3 undoes the multiplication by 3.
y=x-3
Divide -9+3x by 3.
