The expression given is $x + 8$.

This expression represents a value that is 8 units more than $x$. Without further context, this is a simplified algebraic expression and cannot be solved unless additional information (like the value of $x$) is provided.

Would you like to explore solving for $x$ if an equation was provided, or do you have any specific context in mind?

Here are 5 related questions to explore further:

1. How would you solve for $x$ if the expression was set equal to a number, like $x + 8 = 15$?
2. What happens to the value of the expression $x + 8$ if $x$ is negative?
3. Can you think of a real-world scenario where $x + 8$ might represent something meaningful?
4. What if you had $x + 8 = y$? How would you solve for $x$ in terms of $y$?
5. How does the graph of $y = x + 8$ look compared to the graph of $y = x$?

Tip: In algebra, expressions like $x + 8$ can be used to model and solve a wide range of real-world problems, especially when you set them equal to other values or expressions.
