How do I get a matrix with its vector in reduced row-echelon form?

I want to get the reduced row-echelon form of the matrix with its vector(b) in the rref. For example if the matrix and vector is in te form [A|b] I want that rref.

Use the matrix you described to solve the matrix equation.

If you also want the inverse of ‘A’, horizontally concatenate an identity matrix the same size as ‘A’ to the matrix you described.

I leave the rest to you.

Experiment to get the result you want.
