Inconsistent reduced row echelon form
A system of linear equations is said to be in row echelon form if its augmented matrix is in row echelon form. Similarly, a system of linear equations is said to be in reduced row echelon form or in canonical form if its augmented matrix is in reduced row echelon form. The canonical form may be viewed as an explicit solution of the linear system. In fact, the system is inconsistent if and only if one of the equations of the canonical form is reduced to 0 = 1. Other… WebA system of equations is called inconsistent if it has no solution. It is con-sistent otherwise. SECTION 1.2. Definition. A matrix is in row echelon form if ... A matrix is in reduced row echelon form if it is in row echelon form, and in addition, (4)The pivot in each nonzero row is equal to 1. (5)Each pivot is the only nonzero entry in its ...

WebType 2: Multiply a row by a nonzeroscalar. Type 3: Add to one row a scalar multiple of another. Because these operations are reversible, the augmented matrix produced always represents a linear system that is equivalent to the original. The last matrix is in reduced row echelon form, and represents the systemx= −15,y= 8,z= 2.
