There are some chickens and rabbits in the cage. From the top, there are 35 heads, and from the bottom, there are 94 feet. How many chickens and rabbits are there?

Suppose they are all rabbits.

35*4= 140 (only)

140-94=46 (only)

4-2=2 (only)

Chicken: 46/2=23 (only)

Rabbit: 35-23= 12 (only)

A: There are 23 chickens and 0/2 rabbits.

Solution: For every X rabbits, there are (35-x) chickens.

4x+2(35-x)=94

4x+2*35-2x=94

4x+70-2x=94

2x+70=94

2x=24

x= 12

Chicken: 35- 12=23 (only)

A: There are 23 chickens and 0/2 rabbits.
