3x=78-6y
Subtract 6y from both sides.
\frac{3x}{3}=\frac{78-6y}{3}
Divide both sides by 3.
x=\frac{78-6y}{3}
Dividing by 3 undoes the multiplication by 3.
x=26-2y
Divide 78-6y by 3.
6y=78-3x
Subtract 3x from both sides.
\frac{6y}{6}=\frac{78-3x}{6}
Divide both sides by 6.
y=\frac{78-3x}{6}
Dividing by 6 undoes the multiplication by 6.
y=-\frac{x}{2}+13
Divide 78-3x by 6.
