Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4TVBNOW 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。9 k4 I2 ]! U* ]4 n L* H
Formula 4 can change into 11x + 5y = 100 Formula 5 / c/ }0 V' V% p( D. h5 K, ]7 Y# E$ HIn Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. - U3 k2 n) e( h5.39.217.76And 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 = 80.7 @; t, U; z# {9 z- [
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
