Question
**Problem Statement:** Solve the linear system: \[ \begin{cases} x_1 + 3x_2 = 9 \\ 2x_1 + x_2 = 8 \end{cases} \] **Solution Explanation:** To solve this system of equations, you can use methods such as substitution, elimination, or matrix techniques (e.g., Gaussian elimination or using the inverse of a matrix). Here's a brief outline of the substitution method: 1. Solve one of the equations for one variable. 2. Substitute this expression into the other equation. 3. Solve for the remaining variable. 4. Back-substitute to find the first variable's value. You can also interpret this system graphically by plotting each equation as a line on a coordinate plane and finding the intersection point.

**Solve the Linear System** Given the following system of linear equations: 1. \( x_1 - 5x_2 + 2x_3 = -1 \) 2. \( 2x_1 - 10x_2 + 4x_3 = -2 \) You are required to find the values of \( x_1 \), \( x_2 \), and \( x_3 \) that satisfy both equations. This is a typical problem in linear algebra, often solved using techniques such as substitution, elimination, or matrix methods. Note that both equations appear dependent, implying the possibility of infinitely many solutions or a need for a third independent equation.
