Simplify Formula 2 into z, we get z = 100 - x - y Formula 3 . u3 V5 K) f. `; l+ f6 @公仔箱論壇Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4 6 j( W6 s* d' L/ _4 ]Formula 4 can change into 11x + 5y = 100 Formula 55.39.217.763 x5 f9 P) ^4 s& L0 P
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want.tvb now,tvbnow,bttvb2 Q& q: }6 v# e D# ~, ~& M
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.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。# \ s0 ?1 P+ g' W7 Q( H
