FAQ
How does the solver classify the system?
It computes the ranks of A and [A|b] with RREF. If rank(A) = rank([A|b]) = n the solution is unique; if rank(A) = rank([A|b]) < n there are infinitely many solutions; if rank(A) < rank([A|b]) the system is inconsistent.
Can I switch between equation and matrix input?
Yes. Enter equations such as 2x+3y=7 or fill the matrix directly. Examples populate both views and you can share the current setup through the URL.
