Let's distribute and then simplify the given expression $-7(x - 9) + x$.

First, apply the distributive property: $-7 \times x + 7 \times 9 + x$

This simplifies to: $-7x + 63 + x$

Now, combine like terms: $-7x + x = -6x$

Therefore, the simplified expression is: $-6x + 63$

If you have any further questions or need more details, feel free to ask! Here are some related questions you might consider:

1. What would be the result if $x$ has a specific value, say $x = 5$?
2. How would the expression change if the subtraction in the parenthesis was a different operation?
3. What is the process for factoring an expression like $-6x + 63$?
4. Can you graph the equation $y = -6x + 63$ and describe its features?
5. What happens if the sign of the coefficient outside the parenthesis changes, e.g., $7(x - 9) + x$?

Tip: When simplifying expressions, always double-check your arithmetic operations to avoid simple errors.
