Problem A.21 Consider the following theorem: if an n x n matrix A can be transformed into the n x n identity I by a sequence of elementary row operations, then A is nonsingular. The same sequence of operations that transforms A into the identity I will also transform I into A". Use the previous theorem to find the inverse of the given matrix or show that no inverse exists.
