The image contains a system of three linear equations:

1. \( 2x + y - z = 6 \)
2. \( x - y + 2z = -1 \)
3. \( -x + 3y + 0z = 1 \)

Let’s solve this system of equations.

### Step 1: Solve for \( x \) in terms of \( y \) and \( z \) from the first equation.
From the first equation:
\[
2x + y - z = 6
\]
Rearrange for \( x \):
\[
2x = 6 - y + z
\]
\[
x = \frac{6 - y + z}{2}
\]

### Step 2: Substitute into the other equations, or use elimination or matrix methods.

Would you like me to proceed with elimination, substitution, or the matrix method to find \( x \), \( y \), and \( z \)?
