Children, have you ever heard of the problem of "chickens and rabbits in the same cage"? 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 respectively? Using equation and equivalent relation
Suppose there are x chickens, then there are x rabbits,
2x+4x=48
6x=48
x=8
So there are 8 chickens and 8 rabbits
