Solve the formula for the specified variable.
-$I = \frac { n E } { n r + R } \quad$ for $n$
A) $n = \frac { I R } { I r + E }$
B) $n = \frac { - R } { \operatorname { Ir } - \mathrm { E } }$
C) $\mathrm { n } = \mathrm { IR } ( \mathrm { Ir } - \mathrm { E } )$
D) $n = \frac { I R } { E - I r }$

To solve for $n$, multiply both sides by $nr + R$ to get rid of the denominator, then isolate $n$. Rearranging gives $n = \frac{IR}{E - Ir}$.
