Question
Consider the system

\[ \begin{cases} 
x - 2y - 3z = 1 \\
2x + ky + 6z = 6 \\
-x + 3y + (k - 3)z = 0 
\end{cases} \]

**Tasks:**

a. Find all values of \(k\) for which the system has no solutions.

b. Find all values of \(k\) for which the system has a unique solution.

c. Find all values of \(k\) for which the system has infinitely many solutions and write the general solution in this situation.
