Question

•m =x+n/p

•d=f+rx

•-3(x+n)=r

Answer 1

Answer:

Step-by-step explanation:

(1) I'm not sure if the equation is $m = \frac{x + n}{p}$ or $m = x + \frac{n}{p}$, so I'll solve both below.

$m = \frac{x + n}{p}$

$mp = x + n$

$x = mp - n$

$m = x + \frac{n}{p}$

$x = m - \frac{n}{p}$

(2) Answer below

$d = f + rx$

$d - f = rx$

$x = \frac{d - f}{r}$

(3) Answer below

$-3(x + n) = r$

$x + n = \frac{r}{-3}$

$x = \frac{r}{-3} - n$
