    Is the caplock key stuck on your keyboard?

    At first:
    Naomi --- x
    Macy ---- y
    Sebastian -- 234 -x - y

    After the giving:
    Naomi --- x-16 - 24
    Macy --- y + 16
    Sebastian --- 234-x-t + 24

    x-16-24 = 3(y+16) ---> x - 3y = 88
    y+16 = 2(234-x-y+24) --> 2x + 3y = 500

    add them:
    3x = 588
    x = 196
    then in x-3y=88
    196-3y=88
    -3y=-108
    y = 36

    Naomi had 196
    Macy had 36
    Sebastian had 2
