Solution:

To solve the algebraic expression x * 15, we need to multiply the value of x by 15. Let's break down the steps to solve this expression:

Step 1: Identify the value of x
The algebraic expression x * 15 indicates that we need to find the value of x in order to solve the expression. Without any specific value assigned to x, we cannot find an exact numerical solution. Therefore, we will consider x as a variable and proceed with the general solution.

Step 2: Multiply x by 15
The expression x * 15 means multiplying the value of x by 15. Multiplication is the process of repeated addition. When we multiply a number by 15, we are essentially adding the number to itself 15 times. Therefore, the result of x * 15 can be found by adding x to itself 15 times.

Step 3: Simplify the expression
To simplify the expression x * 15, we perform the multiplication operation. Multiplying x by 15 can be represented as x + x + x + x + x + x + x + x + x + x + x + x + x + x + x. This indicates that we are adding x to itself 15 times.

Step 4: Combine like terms
In the expression x + x + x + x + x + x + x + x + x + x + x + x + x + x + x, we can combine the like terms. Since all the terms are the same (x), we can rewrite the expression as 15x. This indicates that we have added x to itself 15 times, resulting in a product of 15x.

Step 5: Final Solution
Therefore, the solution to the algebraic expression x * 15 is 15x. This implies that when x is multiplied by 15, the result is 15 times the value of x.

Summary:
- The algebraic expression x * 15 represents multiplying the value of x by 15.
- To solve the expression, we multiply x by 15, which means adding x to itself 15 times.
- By combining the like terms, the expression simplifies to 15x.
- Therefore, the solution to the expression x * 15 is 15x.
