![**Problem Statement:**
Given the values of \(x = -1\) and \(y = -3\), calculate the value of the expression \(-x - 3y\).
**Solution Approach:**
To solve this problem, we need to substitute the given values of \(x\) and \(y\) into the expression and simplify.
### Step-by-Step Solution:
1. **Substitution:**
\[
-x = -(-1) = 1
\]
\[
-3y = -3(-3) = 9
\]
2. **Combine the results:**
\[
-x - 3y = 1 + 9 = 10
\]
**Final Answer:**
The value of the expression \(-x - 3y\) is 10.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3e0e1a50-ba3f-4042-a2ac-5820bcfd7374%2F7af69f49-92d8-4d03-8b9b-c3bd1f9143d5%2Fyyml1gq_processed.jpeg&w=3840&q=75)
