i need to remember when does Ax=B has a unique solution, more than one, and no solution?(adsbygoogle = window.adsbygoogle || []).push({});

i think that it has a unique solution when A is non singular i.e when det(A) isn't equal zero (at least that's what's written in my notes).

what about more than one solution, what conditipns should be met for either of A,x or b (also for no solution).

i guess that when A isn't non singular then the equation doesnt have solution but im not sure, forgot about this.
