-\frac{3}{5}n-4=\frac{5}{3}x+\frac{20}{3}-4y
Subtract 4y from both sides.
-\frac{3}{5}n=\frac{5}{3}x+\frac{20}{3}-4y+4
Add 4 to both sides.
-\frac{3}{5}n=\frac{5}{3}x+\frac{32}{3}-4y
Add \frac{20}{3} and 4 to get \frac{32}{3}.
-\frac{3}{5}n=\frac{5x}{3}-4y+\frac{32}{3}
The equation is in standard form.
\frac{-\frac{3}{5}n}{-\frac{3}{5}}=\frac{\frac{5x}{3}-4y+\frac{32}{3}}{-\frac{3}{5}}
Divide both sides of the equation by -\frac{3}{5}, which is the same as multiplying both sides by the reciprocal of the fraction.
n=\frac{\frac{5x}{3}-4y+\frac{32}{3}}{-\frac{3}{5}}
Dividing by -\frac{3}{5} undoes the multiplication by -\frac{3}{5}.
n=\frac{20y}{3}-\frac{25x}{9}-\frac{160}{9}
Divide \frac{5x}{3}+\frac{32}{3}-4y by -\frac{3}{5} by multiplying \frac{5x}{3}+\frac{32}{3}-4y by the reciprocal of -\frac{3}{5}.
\frac{5}{3}x+\frac{20}{3}=4y-\frac{3}{5}n-4
Swap sides so that all variable terms are on the left hand side.
\frac{5}{3}x=4y-\frac{3}{5}n-4-\frac{20}{3}
Subtract \frac{20}{3} from both sides.
\frac{5}{3}x=4y-\frac{3}{5}n-\frac{32}{3}
Subtract \frac{20}{3} from -4 to get -\frac{32}{3}.
\frac{5}{3}x=-\frac{3n}{5}+4y-\frac{32}{3}
The equation is in standard form.
\frac{\frac{5}{3}x}{\frac{5}{3}}=\frac{-\frac{3n}{5}+4y-\frac{32}{3}}{\frac{5}{3}}
Divide both sides of the equation by \frac{5}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{-\frac{3n}{5}+4y-\frac{32}{3}}{\frac{5}{3}}
Dividing by \frac{5}{3} undoes the multiplication by \frac{5}{3}.
x=\frac{12y}{5}-\frac{9n}{25}-\frac{32}{5}
Divide 4y-\frac{3n}{5}-\frac{32}{3} by \frac{5}{3} by multiplying 4y-\frac{3n}{5}-\frac{32}{3} by the reciprocal of \frac{5}{3}.
