    I assume you can draw the Venn diagram. The universe is 80, the population outside the circles is 9, the population of the intersection of the circles is 14.

    If you add M+S, you count twice the 14 who passed both.

    so, M + S - 14 = 80-9 = 71
    M + S = 85
    M = 17+S
    2S + 17 = 85
    2S = 68
    S = 34
    so, M = 51
