Math 2240 - Linear Algebra
... Solving a system not in r-e form. • We say that two systems of equations (or equations) are equivalent, if they have exactly the same solutions. • One method of solving a system of equations is to transform it to an equivalent system in r-e form. ...

Discussion
... Gaussian elimination involves the creation of an identity matrix within the augmented matrix [A, B]. In this case, this identity matrix would need to be of dimensions 2x3, but identity matrices are necessarily square. One possibility is to append a third row consisting of only zero entries onto [A, ...
