cN=n
Swap sides so that all variable terms are on the left hand side.
\frac{cN}{c}=\frac{n}{c}
Divide both sides by c.
N=\frac{n}{c}
Dividing by c undoes the multiplication by c.
cN=n
Swap sides so that all variable terms are on the left hand side.
Nc=n
The equation is in standard form.
\frac{Nc}{N}=\frac{n}{N}
Divide both sides by N.
c=\frac{n}{N}
Dividing by N undoes the multiplication by N.
