That is a very simple mathematics question.5.39.217.777 ]8 z1 o% y* F' T

And 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+ |# ?; C3 \' b# Q+ n# n
Eventually, the answer is 20 female and 80 children and no male. |
