-\frac{20}{3}-\frac{7}{3}x=y
Swap sides so that all variable terms are on the left hand side.
-\frac{7}{3}x=y+\frac{20}{3}
Add \frac{20}{3} to both sides.
\frac{-\frac{7}{3}x}{-\frac{7}{3}}=\frac{y+\frac{20}{3}}{-\frac{7}{3}}
Divide both sides of the equation by -\frac{7}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y+\frac{20}{3}}{-\frac{7}{3}}
Dividing by -\frac{7}{3} undoes the multiplication by -\frac{7}{3}.
x=\frac{-3y-20}{7}
Divide y+\frac{20}{3} by -\frac{7}{3} by multiplying y+\frac{20}{3} by the reciprocal of -\frac{7}{3}.
