Let's solve the expression:

\[
5x(9 - (8 - 1)) = ?
\]

1. Start by simplifying inside the parentheses:
   \[
   8 - 1 = 7
   \]
   So the expression becomes:
   \[
   5x(9 - 7)
   \]

2. Simplify further inside the parentheses:
   \[
   9 - 7 = 2
   \]
   Now we have:
   \[
   5x(2)
   \]

3. Finally, multiply:
   \[
   5 \times 2 = 10
   \]

The simplified expression is \(10x\).

Would you like any further details or have questions?

Here are 5 relative questions:
1. How would the expression change if the number inside the parentheses was different?
2. Can you solve \(5x(9-(8+1))\)?
3. What is the value of \(x\) if the entire expression equals 50?
4. How would the result change if \(x = 2\)?
5. What happens if you multiply the entire expression by 2?

**Tip:** Always remember to simplify expressions inside parentheses first when using the order of operations.
