To solve the expression \( x + 8 \) for a specific value of \( x \), you need to set it equal to a solid number, creating an equation. For example, if you want to solve \( x + 8 \) to a solid number like 15, you would set up the equation:

\[
x + 8 = 15
\]

### Steps to Solve:
1. **Subtract 8 from both sides** of the equation to isolate \( x \):

   \[
   x + 8 - 8 = 15 - 8
   \]

2. **Simplify** the equation:

   \[
   x = 7
   \]

So, \( x = 7 \) is the solution.

You can replace 15 with any other number you want, and follow the same steps to solve for \( x \).
