Math application problem: A chicken and a rabbit live in the same cage, with 30 heads and 94 legs. How many chickens and rabbits are there?
Solution 1: There are X chickens and Y rabbits, and the equations are established.

X+Y=30

2X+4Y=94

X= 13,Y= 17。

Solution 2:

Suppose all 30 heads are chickens, then there are 30*2=60 legs.

The extra 34 legs belong to rabbits, so there are 34/2= 17 rabbits.

Then, there are 30- 17= 13 chickens.

Satisfied, please adopt.
