Question

6. Consider the following system of equations, depending on the parameter k. 21 +(k+1):22 +4x3 = 3 +(k+ 3x3 = 21 +222 +3x3 = . Which of the following is true? A) The system has a unique solution for every value of k. B) The system has no solution for any value of k. (C) The solution is unique if k = -1 and k + 2. There are no solutions if k = 2 or if k = -1. D) The solution is unique if k #1 and k #2. There are no solutions if k = 2 and infinitely many if k=-1. E) None of the above.
