WebAfter watching all three reduced row echelon videos I don't understand the following things: what is an "augmented" matrix; why we can perform operations on the matrix without changing the solution; where reduced row echelon comes from (ie where it's form/rules come from); how you know if your solution is a plane, point, etc.; the significance of the … WebAug 4, 2015 · A system is CONSISTENT if it has a unique solution, or infinitely many solutions. When you look at the RREF of a square matrix augmented with the RHS, every complete row of zeros (last column included) corresponds to a free variable. A row of zeros also indicates infinitely many solutions. Therefore, it has to be "consistent" in this context.
