sorry it shows up weird on the screen it's:
2x + 4z = −2
−x + 2y − 3z = 4
x + 2y + z = k
2x + 4z = −2
−x + 2y − 3z = 4
x + 2y + z = k
Row-reduce the augmented matrix for the given system and then answer each of the following questions.
(a) For what value(s) ofk does the system of linear equations have a unique solution?
(b) For what value(s) of k does the system of linear equations have no solution?
(c) For what value(s) of k does the system of linear equations have infinitely many solutions?
(d) For k where the system has infinitely many solutions, solve the system.
