Equation: with X chickens, there are (46-x) rabbits
2x+4(46-x)=128
x+92-2x=64
x=28
Then 46-x = 18
A: there are 28 chickens and 18 rabbits
Formula (I use the halving method): 128 * 2 = 64
64-46 = 18
46-18 = 28
A: there are 28 chickens and 18 rabbits

In a cage, there are chickens and rabbits. They have six heads and 20 feet. How many chickens and rabbits are there in the cage?

If there are x chickens, there are (6-x) rabbits
From the meaning of the title: 2x + 4 (6-x) = 20
 2x+24-4x=20
 2x-4x=20-24
-2x=-4
x=2
6-x=6-2=4
A: there are two chickens and four rabbits

There are 88 counting heads, 23 counting feet, and how many chickens and rabbits are in each cage
It's a formula. It's a formula

There are 23 heads and 88 feet
Suppose there are x chickens and (23-x) rabbits
2x+4(23-x)=88
x=2
23-x=21
There are 21 rabbits and 2 chickens
I remember that there seems to be a special formula in primary school. In fact, it is also evolved from this equation

There are chickens and rabbits in the cage. There are 10 counting heads and 24 counting feet. How many chickens and rabbits are there in the cage?

Let chicken x rabbit be 10-x
2x+4（10-x）=24
