That is a very simple mathematics question.5.39.217.77$ F" p0 Z' m/ w0 N* i! T0 d& t- P

In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.TVBNOW 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 j( @6 M4 b7 h% X* u, P( s1 X
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.
