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
Subtract 3x from 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.
