Sub Formula 3 into Formula 1, we get 6x + 3y + ( 100 - x - y )/2 = 100 Formula 4公仔箱論壇' w* K+ ]* U8 F
Formula 4 can change into 11x + 5y = 100 Formula 5tvb now,tvbnow,bttvb/ ~5 { ]" r3 i* j. y8 _
In Formula 5, x can only be 0 - 9, otherwise y will be negative number which we dont want. ! |8 m# o3 D b& j g& k2 DAnd 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. . `.
