Chickens and rabbits in the same cage, 12 more chickens than rabbits, a total of 72 feet of chickens and rabbits, how many chickens and rabbits each

Chickens and rabbits in the same cage, 12 more chickens than rabbits, a total of 72 feet of chickens and rabbits, how many chickens and rabbits each

If there are x chickens, then there are (72-2x) / 4 rabbits
The countable equation x - (72-2x) / 4 = 12
4x-72+2x=48
6x=120
x=20
20-12=8
So there are 20 chickens and 8 rabbits
The equation is not listed; 4x12 = 48
72+48=120
4+2=6
Chicken; 120 / 6 = 20
Rabbits: 20-12 = 8
So there are 20 chickens and 8 rabbits

There are 28 chickens and 72 rabbits in the same cage. How many chickens and rabbits are there

The easiest way to understand is to use binary equations
28 + rabbit
Chicken * 2 + rabbit * 4 = 72
Kedeji = 20, rabbit = 8
Or if it's all chicken, there should be 56 feet. For each rabbit added, two feet can be added
72-56=16 16/2=8
So there are chickens 20. Rabbits 8

In the same cage, the number of rabbits is twice that of chickens. There are 240 feet, including chickens and rabbits?
Just fill in the numbers
Come on!

In this type of question, we should first understand that the question implies "each chicken has two feet, and each rabbit has four feet". The question tells us that there are 240 feet, and it can be assumed that there are 120 chickens. On this basis, subtracting 2 chickens will increase one rabbit, subtracting 20 chickens will increase 10 rabbits. When there are 24 chickens and 48 rabbits, just meeting the condition of the question, it means that there are 24 chickens and 48 rabbits
