Inconsistent reduced row echelon form

WebNov 3, 2024 · A linear system of equations is inconsistent (does not have a solution) if and only if there is a pivot in the last column of an echelon form of the augmented matrix. I can understand the if part, that is because 0 = 1 is impossible. But how do you prove the only if part? All of the posts I found on this site prove the if part only. WebSep 16, 2024 · Lemma 1.4. 1: Solutions and the Reduced Row-Echelon Form of a Matrix. Let A and B be two distinct augmented matrices for two homogeneous systems of m equations in n variables, such that A and B are each in reduced row-echelon. Then, the two systems do not have exactly the same solutions. Proof. Now, we say that the matrix B is equivalent to …
