    This can be solve by 3 variable equation

    let x be the money of luke

    y money of rachel

    z money of daniel

    first equation

    x = y + 21

    second equation

    x = z + 48

    third equation

    x + y + z = 168

    solving simultaneously

    x = 79

    y = 58

    z = 31
