nC_{3}=20
The equation is in standard form.
\frac{nC_{3}}{n}=\frac{20}{n}
Divide both sides by n.
C_{3}=\frac{20}{n}
Dividing by n undoes the multiplication by n.
C_{3}n=20
The equation is in standard form.
\frac{C_{3}n}{C_{3}}=\frac{20}{C_{3}}
Divide both sides by C_{3}.
n=\frac{20}{C_{3}}
Dividing by C_{3} undoes the multiplication by C_{3}.
