  1. if their ages now are Lee,Kevin,Kate = x,y,z,
    a years ago, Kate was 27
    b years ago, Lee was 38
    x+y+z = 143
    x-a = 27
    z-a = 3(y-a)
    x-b = 38
    2(y-b) = z-b
    Now just solve for x,y,z
    It might be easier to eliminate a and b first, so you just have 3 equations to solve.
