Question
**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.
