$multiply \: second \: equation \: by \: 3 \\ and \: subtract \: first \: equation \: from \: it \\ 3(3m + 2n) - (4m + 6n) = 3(28) - 54 \\ 9m + 6n - 4m - 6n = 30 \\ 5m = 30 \\ m = 6 \\ Substitute \: in \: 1 st \: equation \\ 4(6) + 6n = 54 \\ 6n = 54 - 24 \\ 6n = 30 \\ n = 5 \\ Thus \: m= 6 \: and \: n= 5$

$\bf\star\underline\pink{m= 6 \: and \: n= 5}$
