3x=3-3y
Subtract 3y from both sides.
\frac{3x}{3}=\frac{3-3y}{3}
Divide both sides by 3.
x=\frac{3-3y}{3}
Dividing by 3 undoes the multiplication by 3.
x=1-y
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=1-x
Divide 3-3x by 3.
