Explanation:

Part 1: Choosing a Friend and Calculating Pictures (Taking Brian as an Example)

Step1: Choose a friend (e.g., Brian)

We select Brian from the three friends.

Step2: Sum the pictures Brian made

Brian made 9 (Horses) + 1 (Cats) + 3 (Dogs) pictures. So we calculate $9 + 1 + 3$.
First, $9 + 1 = 10$, then $10 + 3 = 13$.

Step1: Identify the number of each type of picture for Brian

Brian made 9 horse pictures, 1 cat picture, and 3 dog pictures.

Step2: Write the addition equation

To find the total number of pictures, we add the number of each type: $9 + 1 + 3 = 13$.

Answer:

Chosen friend: Brian. Total pictures: 13. (Equation: $9 + 1 + 3 = 13$)

Part 2: Writing the Equation (Using Brian's Data)
