Question
Determine the values of a for which the system has no solutions, exactly one solution, or infinitely many solutions.
x + 2y – 3z = 5
2x – y + 2z = 3
5x + 5y + (a? – 16)z = a + 15
For a =
i
there is no solution.
For a =
i
there are infinitely many solutions.
For a +±
i
the system has exactly one solution.
