    Sounds to me like homework. Also sounds like what one would consider "simplest" would be a matter of personal taste.

    Personally, I think writing the identity matrix beside the given matrix and then using row operations to reduce the matrix to the identity while applying those same operations to the identity matrix is simplest.
