Math Problem Statement

Consider the following system.

x+2y-3z=4

-x-y+5z=-1

2x + 5y-4z=11

Choose the best description of its solution.

If applicable, give its solution.

Solution

Let's analyze the system of equations:

1. & \quad x + 2y - 3z = 4 \\ 2. & \quad -x - y + 5z = -1 \\ 3. & \quad 2x + 5y - 4z = 11 \\ \end{aligned}$$ We'll solve
