30x=2520-70y
Subtract 70y from both sides.
\frac{30x}{30}=\frac{2520-70y}{30}
Divide both sides by 30.
x=\frac{2520-70y}{30}
Dividing by 30 undoes the multiplication by 30.
x=-\frac{7y}{3}+84
Divide 2520-70y by 30.
70y=2520-30x
Subtract 30x from both sides.
\frac{70y}{70}=\frac{2520-30x}{70}
Divide both sides by 70.
y=\frac{2520-30x}{70}
Dividing by 70 undoes the multiplication by 70.
y=-\frac{3x}{7}+36
