  • math -

    You have more information than is needed

    let Glen's present age be x
    then Ben's present age is 4x/7

    in 15 years:
    Glen will be x+15
    Ben will be 4x/7 + 15

    We are told
    x+15 + 4x/7+15 = 63
    7x + 105 + 4x + 105 = 441
    11x = 441 - 210
    11x = 231
    x = 21

    So Glen is now 21 and Ben is now 12

    The fact that "Fifteen years fromnow Ben will be 3/4 as old as Glen" was not needed, but confirms our answer.
