    Simple system of equations problem,
    m = member
    n = nonmember

    1m + 3n = 210
    2m + 1n = 120
    You can multiply the top equation by 2 to get:
    2m + 6n = 420
    2m + 1n = 120
    Then you can subtract the two equations and the members will cancel out (2m – 2m = 0)
    and get:
    5n = 300 so dividing by 5 on both sides you get

    n = 60
    then you can plug in the value of 60 into one of the equations
    2m + 1(60) = 120
    So subtracting 60 u get
    2m = 60
    member = 30
    nonmembers = 60
