Chickens and rabbits in the same cage, a total of 20 heads, 62 legs, ask how many chickens and rabbits each?


There were x chickens and Y rabbits
x+y=20
2x+4y=62
The solution is: x = 9, y = 11
A: there are 9 chickens and 11 rabbits



Chickens and rabbits in the same cage, a total of 35 heads, 94 legs


A: 23 chickens and 12 rabbits
Suppose there are x chickens, then there are 35-x rabbits
The equation is as follows
2X+4(35-X)=94
2X+140-4X=94
-2X=-46
X=23
There are 23 chickens and 35-x = 12 rabbits
