A matrix is in reduced row echelon form (also called row canonical form) if it satisfies the following conditions: • It is in row echelon form. • The leading entry in each nonzero row is a 1 (called a leading 1). • Each column containing a leading 1 has zeros in all its other entries. WitrynaSince all elements of the fourth column are fractions with denominator 3 k − 1, they are determined for all value of k such that the denominator is not equal to zero, i.e.: 3 k − 1 ≠ 0, or k ≠ 1 3. Then, the answer is: the system of linear equations is consistent for k ∈ ( − ∞, 1 3) ∪ ( 1 3, ∞).
