Let x = Male, y = Female, z = Child公仔箱論壇+ c7 q( c* Z* N9 e; }' }

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 b4 a, L2 p. n
Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 45.39.217.76/ U' o& |/ ?& N4 O* P- q
Formula 4 can change into 11x + 5y = 100 Formula 5 " e8 k0 H% {.

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. 1 \- d% d, l5 n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
