1300x=21000-500y
Subtract 500y from both sides.
\frac{1300x}{1300}=\frac{21000-500y}{1300}
Divide both sides by 1300.
x=\frac{21000-500y}{1300}
Dividing by 1300 undoes the multiplication by 1300.
x=\frac{210-5y}{13}
Divide 21000-500y by 1300.
500y=21000-1300x
Subtract 1300x from both sides.
\frac{500y}{500}=\frac{21000-1300x}{500}
Divide both sides by 500.
y=\frac{21000-1300x}{500}
Dividing by 500 undoes the multiplication by 500.
y=-\frac{13x}{5}+42
Divide 21000-1300x by 500.
