**Using Row Operations to Achieve Reduced Row Echelon Form**

In this section, we will use row operations to transform the given matrix into its reduced row echelon form.

The initial augmented matrix is:

\[
\begin{pmatrix}
1 & 1 & 1 & | & 16 \\
4 & 5 & 8 & | & 32 \\
\end{pmatrix}
\]

Your task is to perform row operations to simplify this matrix step by step.

We start with the same initial matrix in each case:

\[
\begin{pmatrix}
1 & 1 & 1 & | & 16 \\
4 & 5 & 8 & | & 32 \\
\end{pmatrix}
\]

The goal is to convert this matrix into the form:

\[
\begin{pmatrix}
[ ] & [ ] & [ ] & | & [ ] \\
[ ] & [ ] & [ ] & | & [ ] \\
\end{pmatrix}
\]

Where each blank space represents an element of the transformed matrix. 

To achieve reduced row echelon form, you will use the following row operations:
- Swapping two rows.
- Multiplying a row by a nonzero scalar.
- Adding or subtracting the multiple of one row to another row.

By applying these operations systematically, you will simplify the matrix to its reduced form, making it easier to solve the system of linear equations it represents.
