    General question about row reduction.

    If i have an end result that has a row of 0's in A but numbers in b, is that a definite sign that something is wrong?

    so I'll end up with something like

    0x1 + 0x2 + 0x3 = a+b+c

    Obviously 0 != any number.

    No, it isn't. That equation provides a necessary (not sufficient) condition for the system to be compatible: a+b+c=0 .
