Question

M=p/n+4 make n the subject​

Answer 1

`m = (p)/((n + 4)) \\ (n + 4)m = p \\ nm + 4m = p \\ nm = p - 4m \\ n = (p - 4m)/(m) \\ n =( (p)/(m) - 4)`

n=p/m-4 is the right answer.

Answer 2

`n = \frac {p - 4m}{m}`

Explanation:

Given the algebraic expression;

`m = \frac {p}{n + 4}`

To make n the subject of formula.

Cross-multiplying, we have;

`m*(n+4) = p`

`mn + 4m = p`

Rearranging the equation, we have;

`mn = p - 4m`

`n = \frac {p - 4m}{m}`
