2x=20+7y
Add 7y to both sides.
2x=7y+20
The equation is in standard form.
\frac{2x}{2}=\frac{7y+20}{2}
Divide both sides by 2.
x=\frac{7y+20}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{7y}{2}+10
Divide 20+7y by 2.
-7y=20-2x
Subtract 2x from both sides.
\frac{-7y}{-7}=\frac{20-2x}{-7}
Divide both sides by -7.
y=\frac{20-2x}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{2x-20}{7}
Divide 20-2x by -7.
