In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. : ]$ ^5 {! k4 Z7 N6 ]1 E" |7 t5.39.217.76And between 0 and 9, only 0 can give me a single number of y. So, x has to be 0 and y have to be 20. Then put x and y back to formula 1, we get z = 80. , U9 l, C7 O" o2 O- _6 Utvb now,tvbnow,bttvbEventually, the answer is 20 female and 80 children and no male.作者: alan1234 時間: 2007-10-14 12:19 AM 標題: two answers
