The expression you're asked to evaluate is $|x - 5y|$, where $x = 3$ and $y = -3$.

To find the value, substitute $x = 3$ and $y = -3$ into the expression:

$|x - 5y| = |3 - 5(-3)|$

Simplify inside the absolute value:

$= |3 + 15| = |18|$

Since the absolute value of 18 is 18, the value of the expression is:

$18$

Would you like any further clarification on this? Here are some related questions to deepen your understanding:

1. What is the definition of absolute value and how does it affect negative numbers?
2. How would you evaluate $|x - 5y|$ if $x = -2$ and $y = 4$?
3. What are some common mistakes when simplifying expressions with absolute value?
4. Can you simplify $|x + 3| - |y - 1|$ with specific values for $x$ and $y$?
5. How can you graph absolute value functions like $y = |x|$?

Tip: Remember, the absolute value of any number represents its distance from zero on the number line, so the result is always non-negative.
