Answer 2

Answer:

(m,n) = (6,5)

Step-by-step explanation:

$4m + 6n = 54 \\ 3m + 2n = 28 \\ - - - - - - - - - - - - - - - \\ 4m + 6n = 54 \\ 9m + 6n = 84 \\ - - - - - - - - - - - - - - - \\ 4m - 9m = 54 - 84 \\ 5m = 30 \\ m = \frac{30}{5} \\ m = 6 \\ \\ 3m + 2n = 28 \\ 3(6) + 2n = 28 \\ 18 + 2n = 28 \\ 2n = 10 \\ n = \frac{10}{2} \\ n = 5$
