Formula 4 can change into 11x + 5y = 100 Formula 5 9 W2 E/ _ @7 ]; |; {tvboxnow.comIn Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. $ o2 n2 W6 S5 J A3 q8 Ntvboxnow.comAnd 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.tvboxnow.com5 a2 [3 ?5 K8 @; r1 o
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
