Question:
In problem use Theorem II.3 to find A^{1} for the given matrix or show that no inverse exists.
Theorem II.3
If an n × n matrix A can be transformed into the n × 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^{1}.
