0a - 2b + 3c = 1(adsbygoogle = window.adsbygoogle || []).push({});

3a + 6b - 3c = -2

6a + 6b + 3c = 5

I got a = 3, b = 3/2, c = -4/3 but the book says that this system is inconsistent. It asks us to use Gauss-Jordan elimination (which I have used on the past 5 or so problems and got all the right answers). I know how to do these, I just don't see where my mistake is. I am probably looking over some very simplistic reason why it is inconsistent... Any help is appreciated.
