The chicken has two legs, the rabbit has four or four legs, and the chicken rabbit has a total of 746 and 1758 legs, so there are 133 rabbits and 613 chickens.
-
Answer: Rabbits have two more legs than chickens, if each chicken adds two more legs, then 49 chickens and rabbits have a total of 49 * 4 = 196 legs 196-100 = 96 This extra leg is artificially added by us, each chicken adds two So there is a total of 96 2 = 48 chickens 1.
-
This one is very simple, because there are a total of 1758 legs, and then -100 746 2 equals 1492 legs, and the remaining 266 legs are the two legs of the rabbit! 266 2 = 133 rabbits! 133*4=532,1758-532=1226,1226/2=613。
613 chickens!

Chickens and rabbits in the same cage can be used to assume that the whistle is blowing and the foot is raised.
Blowing twice and lifting two feet, the remaining legs have 1758-746*2=266 (all that is left are the two feet of rabbits), 266 2=133 rabbits.
The number of chickens is 746-133 = 613.
-
Let's say it's all chickens. 746 2 = 1492 articles.
Rabbits: (1758-1492) (4-2) = 133.
Chickens: 746-133 = 613 chickens.
-
Uh, this is the eh, there is that elimination method to exclude that leg, and then two legs are fine, and the remaining two legs are rabbits.
-
In that case, if you want to count the legs of the same, it is still a binary equation that is more troublesome to calculate.
-
You can do this in an easy way, with a chicken and rabbit in a cage with one foot or one arm extended.

Hello, according to the topic, the example is as follows:
746 2 = 1492 articles.
1758-1492 266 (article).
Rabbits: 266 4-2) 133 (only).
Chickens: 746-133 = 613 chickens.
A: There are 613 chickens. 133 rabbits.
-
There are a total of 746 chickens and rabbits, with only 1758 legs, how many chickens are there? I did the math and there were 286 chickens.
-
The odd rabbit has a total of 746 AD and 1758 legs, and I think there should be 500 chickens.
-
There are a total of 746 chickens and rabbits, and 91,758 legs of headphones are very good.
-
1758-2x746)÷(4-2)=133
There are 746 chickens and rabbits with 1,758 legs, and 613 chickens.

This kind of question is an IQ question, you don't have to think about it too complicated, it's just a simple one.
-
There were 78 chickens and rabbits. There are 200 legs, 56 chickens and 22 rabbits.
According to the title, if there are x chickens, then there are 78-x rabbits.
Column equation: 2x+(78-x) 4=200
2x+312-4x=200
2x=312-200
x=56 rabbits: 78-56=22.
So 56 chickens and 22 rabbits.
-
Chicken + Rabbit = 78 2 Chicken + 2 Rabbit = 156
2 chickens + 4 rabbits = 200 (chicken with two legs, rabbit with four legs).
The lower formula minus the upper formula is.
2 rabbit = 44, rabbit = 22 (only), bring in the first formula for.
Chicken = 78-22 = 56 (pcs).
-
Equation: Let there be x chickens and y rabbits.
The solution is x=56 y=22
-
Summary. Hello, let's assume that the rabbit lifts two feet, all of which are chicken feet, a total of 78 2 = 156 feet, which is 44 feet less, so the raised rabbit feet are 44, since the rabbit has four legs, 44 2 = 88 is the total number of rabbits, and 88 4 = 22 is the number of rabbits.
There were 78 chickens and rabbits. There are 200 legs, how many chickens and rabbits are there?
Hello, I am helping you to inquire about the relevant information and will reply to you immediately.
In the fourth grade of primary school, you cannot use equations.
Hello, this is a typical chicken-rabbit problem, assuming that 78 are all chickens, then the feet should be 2 78 = 156, which is 200-156 = 44 less than the known 200 feet, because 1 chicken is less than a rabbit: 4-2 = 2 feet, so what is less is the rabbit's feet, the rabbit has 44 2 = 22 (chickens), then the chicken has 78-22 = 56 (chickens).
I still don't understand it, can you say it more clearly?
Hello, let's assume that the rabbit lifts two feet, all of which are chicken feet, a total of 78 2 = 156 feet, which is 44 feet less, so the raised rabbit feet are 44, since the rabbit has four legs, 44 2 = 88 is the total number of rabbits, and 88 4 = 22 is the number of rabbits.
Do you get the idea?
-
The established equation is: 2 chickens + 4 (78-chickens) = 200
Chickens = 56, rabbits = 78-56 = 22.
-
If there are x chickens, then there are x -36 rabbits. 2 x + x -36) *4 = 792 ==2x + 4x - 144 = 792 ==6x = 936 ==x = 156 x -36 = 136 - 36 = 100

This is a simple chicken-rabbit cage problem, as long as the chicken and rabbit are xy, and then solve the equation.
If you encounter similar problems in the future, you can follow the following ideas to solve them:
1. Finding problems: often living in the world, always in these kinds of contradictions, when some contradictions are projected into consciousness, the individual only finds that he is a problem, and asks to find a way to solve it. This is the stage where the problem is discovered.
From the perspective of the stage of problem solving, this is the first stage and the premise of solving the problem.
2. Analyze the problem: In order to solve the problems found, it is necessary to clarify the nature of the problems, that is, to figure out what contradictions there are, which contradictions, and what is the relationship between them, so as to clarify what results the problems to be solved, the conditions that must be met, the relationships between them and what conditions have been met, so as to find out the important contradictions and key contradictions.
3. Put forward hypotheses: on the basis of analyzing the problem, put forward hypotheses to solve the problem, that is, the solution that can be adopted, including what principles and specific ways and methods to take, but all of these are often not ready-made, and there are a variety of possibilities. However, putting forward hypotheses is the key stage of problem solving, and correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions lead to detours or lead the solution of the problem astray.
4. Verify the hypothesis: The hypothesis only proposes n possible solutions, and there is no guarantee that the problem will be solved, so the last step in problem solving is to test the hypothesis. In either case, if the test does not produce the expected result, the hypothesis must be re-tested until the correct result is obtained, and the problem is solved.
Suppose all 100 chickens are chickens, then the total number of feet is 2 100 = 200 (chickens) The number of rabbit feet is 0, and there are 200 more chicken feet than rabbit feet, when in fact there are 16 fewer chicken feet than rabbit feet. Therefore, the difference between chicken feet and rabbit feet is more than known (200 + 16) = 216 (only), because the rabbit in it is replaced by a chicken. For each rabbit that is replaced with a chicken, the number of chickens will increase by 2 and the number of rabbit feet will decrease by 4. >>>More
