If there are x chickens, X rabbits, x-20 rabbits
Then 4 (x-20) - 2x = 200
The solution is x = 140
So x-20 = 120
A: there are 140 chickens and 120 rabbits



The number of chickens and rabbits is the same. The total number of legs of the two animals is 48. How many chickens and rabbits are there?


Suppose a chicken has x legs and a rabbit has 2x legs, then the equation x + 2x = 48 gives x = 16 16 / 2 = 8, so there are 8 chickens and 8 rabbits



"The number of chickens and rabbits is the same. The total number of legs of the two animals is 48. How many chickens and rabbits are there? We need to use the equation to solve it!


Suppose there are x chickens, then there are x rabbits
2x+4x=48
x=8
So there are eight chickens and eight rabbits
