Answer:
[tex] n = \frac {p - 4m}{m} [/tex]
Step-by-step explanation:
Given the algebraic expression;
[tex] m = \frac {p}{n + 4} [/tex]
To make n the subject of formula.
Cross-multiplying, we have;
[tex] m*(n+4) = p [/tex]
[tex] mn + 4m = p[/tex]
Rearranging the equation, we have;
[tex] mn = p - 4m [/tex]
[tex] n = \frac {p - 4m}{m} [/tex]
Answer:
[tex]m = \frac{p}{(n + 4)} \\ (n + 4)m = p \\ nm + 4m = p \\ nm = p - 4m \\ n = \frac{p - 4m}{m} \\ n =( \frac{p}{m} - 4)[/tex]
