-x=-3-3y
Subtract 3y from both sides.
-x=-3y-3
The equation is in standard form.
\frac{-x}{-1}=\frac{-3y-3}{-1}
Divide both sides by -1.
x=\frac{-3y-3}{-1}
Dividing by -1 undoes the multiplication by -1.
x=3y+3
Divide -3-3y by -1.
3y=-3+x
Add x to both sides.
3y=x-3
The equation is in standard form.
\frac{3y}{3}=\frac{x-3}{3}
Divide both sides by 3.
y=\frac{x-3}{3}
Dividing by 3 undoes the multiplication by 3.
y=\frac{x}{3}-1
Divide -3+x by 3.
