Web let us work through a few row echelon form examples so you can actively look for the differences between these two types of matrices. Left most nonzero entry) of a row is in column to the right of the leading entry of the row above it. To solve this system, the matrix has to be reduced into reduced echelon form. Example 1 label whether the matrix provided is in echelon form or reduced echelon form: The first nonzero entry in each row is a 1 (called a leading 1). We immediately see that z = 3, which implies y = 4 − 2 ⋅ 3 = − 2 and x = 6 − 2( − 2) − 3 ⋅ 3 = 1. Only 0s appear below the leading entry of each row. Hence, the rank of the matrix is 2.
