The number of chickens and rabbits is the same. Two animals have 48 legs in total. How many chickens and rabbits are there?
The number of chickens and rabbits is the same. The legs of two animals add up to 48, and chickens and rabbits each have 8.

According to the meaning of the question

Suppose: there are x chickens, so there are x rabbits.

Column equation:

2x+4x=48

6x=48

x=8

So there are eight chickens and rabbits.

Extended data:

When calculating an equation, x is not necessarily placed on the left side of the equation, or there are two x's in an equation, so it needs to be solved by simple calculation methods in mathematics. Some formulas have an X on the right, which can be simply calculated in a different position.

Use the rule of removing parentheses to remove parentheses from the equation.

4x+2(79-x)= 192

Solution: 4x+ 158-2x= 192.

4x-2x+ 158= 192

2x+ 158= 192

2x= 192- 158

x= 17
