solvefor I=(PN)/(RN+A),N

solve for

I = \frac{PN}{RN + A}, N

N = - \frac{I A}{I R - P}; I R - P \neq = 0

Solution steps

I = \frac{PN}{RN + A}

Multiply both sides by

RN + A

I (RN + A) = NP

Expand

I (RN + A) : N I R + I A

N I R + I A = NP

Move

I A

to the right side

N I R = NP - I A

Move

NP

to the left side

N I R - NP = - I A

Factor

N I R - NP : N (I R - P)

N (I R - P) = - I A

Divide both sides by

I R - P; I R - P \neq = 0

N = - \frac{I A}{I R - P}; I R - P \neq = 0

\frac{- 2}{x} = \frac{7}{x - 9} - 1

\frac{4}{r} = \frac{r}{9}

1 0^{5} = \frac{10}{b ^{3}}

\frac{42}{x} = 7

\frac{4}{x + 2} = \frac{9}{3 x}
