3x=108-6y
Subtract 6y from both sides.
\frac{3x}{3}=\frac{108-6y}{3}
Divide both sides by 3.
x=\frac{108-6y}{3}
Dividing by 3 undoes the multiplication by 3.
x=36-2y
Divide 108-6y by 3.
6y=108-3x
Subtract 3x from both sides.
\frac{6y}{6}=\frac{108-3x}{6}
Divide both sides by 6.
y=\frac{108-3x}{6}
Dividing by 6 undoes the multiplication by 6.
y=-\frac{x}{2}+18
Divide 108-3x by 6.
