Question

Solve for the indicated variable
I = E/r+R/n;n

Answer 1

\[I=E \div r+ \left(\begin{matrix}R \\ n\end{matrix}\right)\]

Answer 2

I = E/r + R/N
I - E/r = R/N (subtract E/r from both sides)
N(I - E/r) = R (multiply both sides of equation by N, to get N out of the denominator)
N = R/(I - E/r) (divide both sides of equation by I - E/r)

Answer 3

use n instead

Answer 4

I can't subtract E/r
