Please show all work written and clearly

Solve the following system and use parametric equations to describe the solution set.

\[
\begin{align*}
x_1 + 2x_2 + 3x_3 &= 11 \\
2x_1 - x_2 + x_3 &= 2 \\
3x_1 + x_2 + 4x_3 &= 13 \\
\end{align*}
\]

Recall how we use parameters to express infinitely many solutions. If confused, rewatch the recorded video where we did it. Show all the steps of Gaussian elimination.
