I'm currently practicing some Gaussian elimination questions for my discrete math topic, I came across this question and I need help. How can I justify whether I'm able to apply the Gaussian elimination method to this system?
Question:
Consider the following system of linear equations.
$$\begin{eqnarray*}a_{12}y + a_{13}z &=& b_1 \\ a_{21}x + a_{23}z &=& b_2 \\ a_{31}x + a_{32}y &=& b_3\end{eqnarray*}$$
Can you apply Gaussian elimination to this system? Justify your answer.
