Solve the formula for the indicated variable.
-$\mathrm { R } = \mathrm { nE } - \mathrm { nr }$, for $\mathrm { n }$
A) $\mathrm { n } = \frac { \mathrm { R } } { \mathrm { E } - \mathrm { r } }$
B) $n = R - E + r$
C) $\mathrm { n } = \mathrm { R } + \mathrm { nr } - \mathrm { E }$
D) $n = \frac { R + n r } { E }$

To solve for $n$, factor it out on the right side of the equation: $R = n(E - r)$. Then, divide both sides by $(E - r)$ to isolate $n$, resulting in $n = \frac{R}{E - r}$.
