I have rabbits abd chickens. Between them, I count 35 heads. How many rabbits and how many chickens do I have?

35 altogether. each has one head.

If you start with 98 legs and have 35 heads. You would have 14 rabbits with 56 feet. 98 total legs minus 56 for the rabbits equal 42 feet left. Divide 42 by 2 legs for each bird equal 21 birds. 14 rabbits and 21 birds equal 35 heads with 98 total feet.

To solve this problem, we can use a system of equations to represent the information given. Let's denote the number of rabbits as "R" and the number of chickens as "C".

According to the information provided, you have a total of 35 heads, which means the sum of rabbits and chickens is 35. So, we have our first equation: R + C = 35.

Since both rabbits and chickens have one head each, we can also write the equation for the total number of heads as: 1*R + 1*C = 35.
Simplifying this equation, we get a second equation: R + C = 35.

As you can see, both equations are the same. Therefore, there are multiple solutions to this problem. We need more information or constraints to determine the exact number of rabbits and chickens.
