Question
State the # of solutions and write the solution set of this augmented matrix

Transcribed Image Text:The image shows an augmented matrix often used in linear algebra to represent systems of linear equations. The matrix is presented as follows:
```
⎛ ⎞
⎜ 1 0 1 | 2 ⎟
⎜ 0 1 -2 | 3 ⎟
⎜ 0 0 0 | 0 ⎟
⎝ ⎠
```
This matrix is composed of two parts separated by a vertical bar. The left part represents the coefficients of the variables in the system, while the right part represents the constants from the equations.
- The first row corresponds to the equation: \(1x + 0y + 1z = 2\).
- The second row corresponds to the equation: \(0x + 1y - 2z = 3\).
- The third row indicates a trivial equation, \(0 = 0\), which may suggest that the system has either infinitely many solutions or is consistent under certain conditions.
This matrix form is commonly used when applying row operations to solve systems of equations using methods such as Gaussian elimination or the Gauss-Jordan method.
