140x=5200-30y
Subtract 30y from both sides.
\frac{140x}{140}=\frac{5200-30y}{140}
Divide both sides by 140.
x=\frac{5200-30y}{140}
Dividing by 140 undoes the multiplication by 140.
x=-\frac{3y}{14}+\frac{260}{7}
Divide 5200-30y by 140.
30y=5200-140x
Subtract 140x from both sides.
\frac{30y}{30}=\frac{5200-140x}{30}
Divide both sides by 30.
y=\frac{5200-140x}{30}
Dividing by 30 undoes the multiplication by 30.
y=\frac{520-14x}{3}
Divide 5200-140x by 30.
