Section 1.5 Reduced Echelon Form 10 r If we get then the solution is 01 s x1= r and x =2s. 0 r 0 s If we get 001 t then the solution is x1= r, x2= s and x =3t. With many systems, particularly rectangular systems, this isn't possible. We need a form to show us when the augmented matrix is "as reduced as possible". Reduced Echelon Form All four of these conditions must be met: (1) All rows that consist entirely of zeros are at the bottom. (2) In a nonzero row, the first nonzero entry from the left is a 1. This is called a "leading one". (3) The leading ones form a stairstep pattern down and right. (4) The leading one in each
