Question
**Solving a System of Linear Equations Using Row Reduction**

To solve the following system of linear equations, we will use the method of row reduction. By transforming the augmented matrix of the system to its reduced row echelon form, we can find the solutions.

Given system of equations:
\[ \begin{cases} 
x - 2y + 3z = -6 \\ 
-x + 3y - 5z = 13 \\ 
-2x + y - 3z = 0 
\end{cases} \]

### Step 1: Write the Augmented Matrix
First, we represent the system of equations as an augmented matrix:
\[
\begin{pmatrix}
1 & -2 & 3 & | & -6 \\
-1 & 3 & -5 & | & 13 \\
-2 & 1 & -3 & | & 0 \\
\end{pmatrix}
\]

### Step 2: Perform Row Operations to Achieve Row Echelon Form

**(a) Row 1 (R1):** 
\[
\begin{pmatrix}
1 & -2 & 3 & | & -6 \\
-1 & 3 & -5 & | & 13 \\
-2 & 1 & -3 & | & 0 
\end{pmatrix}
\]

**(b) Row 2 (R2) → R2 + R1:**
\[
\begin{pmatrix}
1 & -2 & 3 & | & -6 \\
0 & 1 & -2 & | & 7 \\
-2 & 1 & -3 & | & 0 
\end{pmatrix}
\]

**(c) Row 3 (R3) → R3 + 2R1:**
\[
\begin{pmatrix}
1 & -2 & 3 & | & -6 \\
0 & 1 & -2 & | & 7 \\
0 & -3 & 3 & | & -12 
\end{pmatrix}
\]

**(d) Row 3 (R3) → R3 + 3R2:**
\[
\begin{pmatrix}
1 & -2 & 3 & | & -6 \\
0 & 1 & -2 & | & 7 \\
0 &
