Question

Use the Gauss–Jordan method to determine whether
the following linear system has no solution, a unique solution, or an infinite number of solutions. Indicate the solutions (if any exist).

 

The image contains a system of linear equations. The equations are as follows:

1. \( x_1 + x_2 + x_4 = 3 \)
2. \( x_2 + x_3 = 4 \)
3. \( x_1 + 2x_2 + x_3 + x_4 = 8 \)

This is a system of three equations with four variables, \(x_1\), \(x_2\), \(x_3\), and \(x_4\). Solving such systems often involves finding values for these variables that satisfy all equations simultaneously. Methods such as substitution, elimination, or matrix operations can be used to find the solutions, if any exist.
