20x=10200-30y
Subtract 30y from both sides.
\frac{20x}{20}=\frac{10200-30y}{20}
Divide both sides by 20.
x=\frac{10200-30y}{20}
Dividing by 20 undoes the multiplication by 20.
x=-\frac{3y}{2}+510
Divide 10200-30y by 20.
30y=10200-20x
Subtract 20x from both sides.
\frac{30y}{30}=\frac{10200-20x}{30}
Divide both sides by 30.
y=\frac{10200-20x}{30}
Dividing by 30 undoes the multiplication by 30.
y=-\frac{2x}{3}+340
Divide 10200-20x by 30.
