20x=1300-40y
Subtract 40y from both sides.
\frac{20x}{20}=\frac{1300-40y}{20}
Divide both sides by 20.
x=\frac{1300-40y}{20}
Dividing by 20 undoes the multiplication by 20.
x=65-2y
Divide 1300-40y by 20.
40y=1300-20x
Subtract 20x from both sides.
\frac{40y}{40}=\frac{1300-20x}{40}
Divide both sides by 40.
y=\frac{1300-20x}{40}
Dividing by 40 undoes the multiplication by 40.
y=\frac{65-x}{2}
Divide 1300-20x by 40.
