Question

M+2=7/n make n the subject​

Answer 1

Answer:

$n = \frac{7}{m + 2}$

Step-by-step explanation:

$m + 2 = \frac{7}{n}$

To make n as the subject , we need to isolate it.

■ Lets multiply n on both the sides in order to shift n to the L.H.S.

$= > n(m + 2) = \frac{7}{n} \times n$

$= > n(m + 2) = 7$

■ Lets now divide (m + 2) on both the sides in order to isolate n in L.H.S

$= > \frac{n(m + 2)}{( m+ 2)} = \frac{7}{(m + 2)}$

$= > n = \frac{7}{m + 2}$
