6x=18-6y
Subtract 6y from both sides.
\frac{6x}{6}=\frac{18-6y}{6}
Divide both sides by 6.
x=\frac{18-6y}{6}
Dividing by 6 undoes the multiplication by 6.
x=3-y
Divide 18-6y by 6.
6y=18-6x
Subtract 6x from both sides.
\frac{6y}{6}=\frac{18-6x}{6}
Divide both sides by 6.
y=\frac{18-6x}{6}
Dividing by 6 undoes the multiplication by 6.
y=3-x
Divide 18-6x by 6.
