Two augmented matrices for two linear systems in the variables x, y, and z are given below. The augmented matrices are in reduced row-echelon form. For each system, choose the best description of its solution. If applicable, give the solution:
(a)
The system has no solution.
The system has a unique solution.
-2
2
(x, y, z) = ODD
The system has infinitely many solutions (x, % 2) =
(DD
(DvD
Olz)
The system has no solution.
The system has a unique solution.
-3
-8
(x, y, z) = ODD
The system has infinitely many solutions (x, % 2) =
(DD
OyD)
0#z)
