I am not sure how to solve this:(adsbygoogle = window.adsbygoogle || []).push({});

Given an augmented matrix, find conditions on a, b, c for which the system has solutions:

so by Gaussian elimination, the matrix I ended up with isCode (Text):

-1 -2 3 b

-1 -6 23 c

-3 2 4 a

And now I am stuck, because there is still a variable left in the last row. Does that mean there are no such a, b, c for which the system has a solution?Code (Text):

1 2 -3 -b

0 4 -20 b-c

0 0 -35 (3b-a) + 2(b-c)

Thanks in advance.
