Express A as a product of elementary matrices.  Expressing the inverse of A as elementary matrices won't be good enough.  Include every bit of your reasoning so that you produce a solution that is clear, complete, and detailed.  Make sure you use our notation for elementary matrices.  Do NOT use the  R1 + R2 = R1 business. And do not use determinants
