Question

Solve
4m + 3n +24 = 0 ,7m-2n +13 =0​

Answer 1

${\huge{\boxed{\blue{Answer}}}}$

$4m + 3n + 24 = 0----(1) \\ 7m - 2n + 13 = 0----(2)$

$\underline{multiply \: (1) \: by \: 2 \: and \: (2) \: by \: 3}$

$= > 8m + 6n + 48 = 0---(3) \\ \: \: \: \: \: \: \: \: 21m - 6n + 39 = 0---(4)$

$\underline{now \: add \: (3) \: and \: (4)}$

$= > 29m + 87 = 0$

$= > 29m = - 87$

$= > m = \frac{ - 87}{29}$

$= > m = - 3$

$\underline{put \: m = - 3 \: in \: (1)}$

$= > 4( - 3) + 3n = - 24$

$= > - 12 + 3n = - 24$

$= > 3n = - 24 + 12$

$= > 3n = - 12$

$= > n = \frac{ - 12}{4}$

$= > n = - 4$
