Answer 1

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{p = \frac{m - 2n}{3}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{p = 15}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{m = 9}$

$\: \: \: \: \: { \bold \pink{according \: to \: question}}$

$⇢\: \: \: \: \: \: \: \: \sf{15 = \frac{9 - 2n}{3}}$

$⇢ \: \: \: \: \: \: \: \: \sf{45 = 9 - 2n}$

$⇢ \: \: \: \: \: \: \: \: \sf{2n = - 36}$

$⇢ \: \: \: \: \: \: \: \: \: \: \sf{n = - 18}$

Answer 2

Solution :-

${ \mathfrak{we \: are \: given \: the \: values \: of \: p \: and \: m}}$

$\red{ \fbox{so \: we \: will \: put \: it}}$

$p = \frac{m - 2n}{3} \\ \\ { \tt{putting \: values \: of \: p \: and \: m}} \\ 15 = \frac{9 - 2n}{3} \\ 15 \times 3 = 9 - 2n \\ 45 = 9 - 2n \\ 45 - 9 = - 2n \\ 36 = - 2n \\ n = \frac{36}{ - 2} \\ n = - 18$

$\huge \dag \: \pink{ \mathfrak{n \: = - 18}} \: \dag$
