  1. from the 2nd ----> m = 5n+54
    sub that into the 1st
    5(5n+54) + n = 36
    25n + 270 + n = 36
    26n = -234
    n = -9
    put that back into m = 5n+54 to get m = +9


    number of scientific -- x
    number of thers ---y

    x+y = 49
    11x 55y = 1859
    reduce that by dividing each term by 11
    x + 5y = 169

    solve the same way as I showed you above
