Simplify Formula 2 into z, we get z = 100 - x - y Formula 3TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。; |5 H' N8 R! R5 F* R
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 42 }3 ~$ t: A+ N# i& k9 A
Formula 4 can change into 11x + 5y = 100 Formula 5 0 ^, M) y# B( L0 Q; D" XIn Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. V" W8 ?* G, \& o- MAnd 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.公仔箱論壇) [+ X+ X$ H3 J3 F# ]
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
