Problem Analysis

We are given a situation where there are puppies playing in a yard. The number of their legs is 21 more than the number of their heads. We need to determine the number of puppies in the yard.

Solution

Let's assume that there are x puppies in the yard. Each puppy has 4 legs and 1 head. According to the given information, the number of legs is 21 more than the number of heads. Therefore, we can set up the following equation:

4x = x + 21

Simplifying the equation, we get:

3x = 21

Dividing both sides of the equation by 3, we find:

x = 7

Therefore, there are 7 puppies in the yard.

Explanation

The equation 4x = x + 21 represents the total number of legs (4x) being 21 more than the total number of heads (x). By solving this equation, we find that x = 7, which means there are 7 puppies in the yard.

This solution assumes that each puppy has 4 legs and 1 head. It is important to note that this is a hypothetical scenario and may not reflect the actual number of legs and heads of puppies in real life.

I hope this explanation helps! Let me know if you have any further questions.
