Question

what is the value of -x + y + z for x = -1, y = -3, and z = 2.

Explanation:

Step1: Substitute the values

Substitute \( x = -1 \), \( y = -3 \), and \( z = 2 \) into the expression \( -x + y + z \). So we get \( -(-1) + (-3) + 2 \).

Step2: Simplify the expression

First, simplify \( -(-1) \) which is \( 1 \). Then the expression becomes \( 1 - 3 + 2 \). Now, calculate \( 1 - 3 = -2 \), and then \( -2 + 2 = 0 \).

Answer:

\( 0 \)
