How do I solve this equation with Gaussian elimination or gauss-Jordan elimination? Please be specific and detailed. The more information, the more I can understand it ## Solving Systems of Equations### Problem StatementConsider the following system of equations:1. \(4x - y + 2z = 15\)2. \(6x + y - z = 3\)3. \(2x + y + 2z = 6\)### ExplanationTo solve these equations, we often use methods like substitution, elimination, or matrix operations. The image shows a handwritten setup for solving a system of linear equations, possibly aimed at using matrix methods for solutions. Here is a step-by-step approach on how one might solve the system:#### Step 1: Represent the System with MatricesThe system can be represented in matrix form \(AX = B\), where:\[A = \begin{bmatrix} 4 & -1 & 2 \\6 & 1 & -1 \\2 & 1 & 2 \end{bmatrix},\quadX = \begin{bmatrix} x \\ y \\ z \end{bmatrix},\quadB = \begin{bmatrix} 15 \\ 3 \\ 6 \end{bmatrix}\]#### Step 2: Perform Row OperationsRow operations can be used to simplify the matrix into a form that is easier to solve, like the row-echelon form or reduced row-echelon form. The matrix operations shown involve transforming the original system to isolate variables step by step.#### Step 3: Back-SubstitutionAfter row operations that create zeros below the pivot, back-substitution can be used to find solutions for \(x\), \(y\), and \(z\).### ConclusionSolving systems of linear equations through matrices involves organizing the coefficients into a matrix, applying row operations, and then using back-substitution to derive the solutions.

How do I solve this equation with Gaussian elimination or gauss-Jordan elimination? Please be specific and detailed. The more information, the more I can understand it

## Solving Systems of Equations

### Problem Statement

Consider the following system of equations:

1. \(4x - y + 2z = 15\)
2. \(6x + y - z = 3\)
3. \(2x + y + 2z = 6\)

### Explanation

To solve these equations, we often use methods like substitution, elimination, or matrix operations. The image shows a handwritten setup for solving a system of linear equations, possibly aimed at using matrix methods for solutions. Here is a step-by-step approach on how one might solve the system:

#### Step 1: Represent the System with Matrices

The system can be represented in matrix form \(AX = B\), where:

\[
A = \begin{bmatrix}
4 & -1 & 2 \\
6 & 1 & -1 \\
2 & 1 & 2
\end{bmatrix},
\quad
X = \begin{bmatrix}
x \\ y \\ z
\end{bmatrix},
\quad
B = \begin{bmatrix}
15 \\ 3 \\ 6
\end{bmatrix}
\]

#### Step 2: Perform Row Operations

Row operations can be used to simplify the matrix into a form that is easier to solve, like the row-echelon form or reduced row-echelon form. The matrix operations shown involve transforming the original system to isolate variables step by step.

#### Step 3: Back-Substitution

After row operations that create zeros below the pivot, back-substitution can be used to find solutions for \(x\), \(y\), and \(z\).

### Conclusion

Solving systems of linear equations through matrices involves organizing the coefficients into a matrix, applying row operations, and then using back-substitution to derive the solutions. This particular setup prepares one to solve the equations using such techniques.
