輪子關(guān)了雞和狗共96支腿雞和狗各多少只

訪客2025-02-18 05:02:151

如雞是X支, 狗是Y支, 用腳來(lái)算2X + 4Y = 96

X + 2Y = 48

因此, 又很多可組成的答案

X = 48 Y = 0X = 36 Y = 6 X = 24 Y = 12 X = 12 Y = 18

X = 46 Y = 1X = 34 Y = 7 X = 22 Y = 13 X = 10 Y = 19

X = 44 Y = 2X = 32 Y = 8 X = 20 Y = 14 X = 8Y = 20

X = 42 Y = 3X = 30 Y = 9 X = 18 Y = 15 X = 6Y = 21

X = 40 Y = 4X = 28 Y = 10X = 16 Y = 16 X = 4Y = 22

X = 38 Y = 5X = 26 Y = 11X = 14 Y = 17 X = 2Y = 23

X = 0Y = 24

同時(shí)關(guān)的話(huà),，只要雞的數(shù)目是偶數(shù)都成立,，如（狗23×4）+雞2×2）等等，分別關(guān)的話(huà)就只有一個(gè)答案,。

你還沒(méi)說(shuō)幾個(gè)頭呢,？,？
