Problem Analysis

We are given that there were 10 puppies being walked, consisting of both dogs and Labradors. The number of Labradors was 4 less than the number of dogs. We need to determine how many Labrador puppies and how many dog puppies were being walked.

Solution

Let's assume the number of dog puppies is represented by x. According to the given information, the number of Labrador puppies is 4 less than the number of dog puppies, so it can be represented as x - 4.

The total number of puppies is the sum of the number of dog puppies and the number of Labrador puppies, which is equal to 10.

Therefore, we can write the equation:

x + (x - 4) = 10

Simplifying the equation:

2x - 4 = 10

Adding 4 to both sides:

2x = 14

Dividing both sides by 2:

x = 7

So, there were 7 dog puppies and 7 - 4 = 3 Labrador puppies being walked.

Answer

There were 7 Labrador puppies and 3 dog puppies being walked.

Explanation

Let's verify the solution using the given information. We were told that there were 10 puppies being walked, and the number of Labrador puppies was 4 less than the number of dog puppies.

If we have 7 dog puppies and 3 Labrador puppies, the total number of puppies is indeed 10. Additionally, the number of Labrador puppies (3) is 4 less than the number of dog puppies (7).

Therefore, our solution is correct.
