The image shows a system of linear equations written in matrix form, where the matrix on the left represents the coefficients of the system, and the vector on the right represents the constants. To solve this system using "normal form," it typically refers to the process of converting the augmented matrix into reduced row echelon form (RREF) or applying Gaussian elimination to find the solutions.

Here is the system represented by the matrix:
\[
\begin{pmatrix}
1 & 2 & 3 & 0 \\
2 & 4 & 3 & 2 \\
3 & 2 & 1 & 3 \\
6 & 8 & 7 & 5
\end{pmatrix}
\]

To solve it using Gaussian elimination, we'll perform the following steps:

### Step 1: Write the augmented matrix
\[
\left[\begin{array}{ccc|c}
1 & 2 & 3 & 0 \\
2 & 4 & 3 & 2 \\
3 & 2 & 1 & 3 \\
6 & 8 & 7 & 5
\end{array}\right]
\]

### Step 2: Perform row operations to reduce the matrix
We aim to get a triangular form, and then back-substitute to find the solutions.

I will calculate the steps.It seems that the matrix has a rank of 3, which means that not all rows are linearly independent. This implies that there might be either no solution or infinitely many solutions depending on the structure of the augmented system.

I'll now proceed to row-reduce the matrix step by step to clarify its solution structure.

### Step 3: Apply Gaussian elimination
Let's break down the row operations needed to transform the matrix into a triangular (or row-echelon) form.

I'll calculate that next.It seems like I can’t do more advanced data analysis right now. Please try again later. 

If you'd like, I can guide you through the manual steps of solving the matrix using Gaussian elimination, or you can upload the problem again for further assistance.

Would you like me to explain the steps in detail?

Here are some related questions:
1. What are the properties of an augmented matrix?
2. How does Gaussian elimination help in solving linear systems?
3. What does the rank of a matrix tell us about its solution set?
4. How can you tell if a system has no solution, one solution, or infinitely many solutions?
5. What role does row-echelon form play in solving matrices?

**Tip:** Always check the rank of a matrix to see if it's consistent with the number of variables before attempting full elimination.

This example demonstrates solving a system of linear equations represented by a matrix using Gaussian elimination and row reduction. The matrix has dimensions 4x4, and key steps include performing row operations to reduce the matrix to triangular form, determining the rank, and analyzing the solutions.
