The image presents a system of linear equations involving five variables, \( x_1, x_2, x_3, x_4, x_5 \), and four equations. Here's the system:

\[
\begin{aligned}
1.\ & 2x_1 + x_2 + 3x_3 - 2x_4 + x_5 = 4 \\
2.\ & 6x_1 + 3x_2 + 5x_3 - 4x_4 + 3x_5 = 4 \\
3.\ & 2x_1 + x_2 + 7x_3 - 4x_4 + x_5 = 12 \\
4.\ & 4x_1 + 2x_2 + 2x_3 - 3x_4 + 3x_5 = 6
\end{aligned}
\]

This is a system of 4 equations with 5 unknowns. Since the number of equations is less than the number of unknowns, this system is **underdetermined**, meaning that we may expect infinitely many solutions or specific dependencies among variables.

Would you like me to proceed with solving this system or explaining a particular method (e.g., Gaussian elimination, matrix representation, etc.)?

### Follow-up Questions:
1. Would you like to solve this system using matrix methods (e.g., Gaussian elimination or row-reduction)?
2. Are you interested in finding a parametric solution for the system, as it may have infinitely many solutions?
3. Would you prefer a step-by-step breakdown of solving this system manually?
4. Do you need an explanation of what it means for a system to be underdetermined and how to interpret solutions?
5. Should I use a specific method such as substitution, or elimination for solving?

**Tip:** Systems with more unknowns than equations often lead to parametric solutions, where one or more variables are expressed in terms of free parameters.
