In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. . k7 X8 f3 u, r.

Then put x and y back to formula 1, we get z = 80. 4 p& B& Q; X+ K2 L7 ^9 [- C$ |公仔箱論壇Eventually, 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
