30x=1620-60y
Subtract 60y from both sides.
\frac{30x}{30}=\frac{1620-60y}{30}
Divide both sides by 30.
x=\frac{1620-60y}{30}
Dividing by 30 undoes the multiplication by 30.
x=54-2y
Divide 1620-60y by 30.
60y=1620-30x
Subtract 30x from both sides.
\frac{60y}{60}=\frac{1620-30x}{60}
Divide both sides by 60.
y=\frac{1620-30x}{60}
Dividing by 60 undoes the multiplication by 60.
y=-\frac{x}{2}+27
Divide 1620-30x by 60.
