{\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
