有頭緒,不過太複雜tvb now,tvbnow,bttvb  u, `+ D" z! u& Q; W& t" \( `
設共有X頭牛,! t5 o2 l/ s7 p. a
四個人共得X頭牛,就有以下等式:
" F" l. i( ?8 x- J" K8 a( ytvb now,tvbnow,bttvb4 w7 E) S( ]8 i& g/ k6 R( s$ E
x/2+0.5+(1-(x/2+0.5))/2+0.5+(1-(1-(x/2+0.5))/2+0.5)/2+0.5+(1-(1-(1-(x/2+0.5))/2+0.5))/2+0.5=x/ y( P7 l7 Z1 M- u& a% B
由於太複雜,暫我時間去計,哈哈
