    These are linear equations that can be solved simultaneously;

    5m+3n=41

    3m-6n=9 (multiplying the first equation by 3 and the second by 5)

    15m+9n=123

    15m-30n = 45 (subtracting the two equations)

    39n = 78

    n = 2,

    and for m, 3m = 9+6 (2)

    = 21

    m = 7

    Therefore, n=2 and m=7
