Use the Gauss-Elimination or Gauss-Jordan Elimination Method approach to solve each linear system below by getting the matrix into Row-Reduced-Echelon-Form. You need to show ALL steps to receive full credit.

What is the augmented matrix? ___________________________

**Problem Statement:**

4. Use the Gauss-Elimination or Gauss-Jordan Elimination Method approach to solve each linear system below by getting the matrix into Row-Reduced Echelon Form. You need to show ALL steps to receive full credit.

\[
\begin{cases} 
2x + 8y - z = 2 \\ 
-x - 3y + z = 1 \\ 
x + 4y - z = 0 
\end{cases}
\]

**Task:**

What is the augmented matrix?

**Explanation:**

To solve the given system of linear equations using the Gauss-Elimination or Gauss-Jordan Elimination Method, first construct the augmented matrix. This involves aligning the coefficients of each variable into columns in a matrix, appending the constants from the right side of the equations as an additional column.

The augmented matrix for the given system is:

\[
\left[\begin{array}{ccc|c}
2 & 8 & -1 & 2 \\
-1 & -3 & 1 & 1 \\
1 & 4 & -1 & 0
\end{array}\right]
\]

The subsequent steps would involve applying the Gauss-Jordan elimination method to transform this matrix into Row-Reduced Echelon Form (RREF). This process includes using elementary row operations to systematically eliminate coefficients below and above each leading entry (also called pivot) to solve for the variables \( x \), \( y \), and \( z \).
