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