At this point, for problems that involve row reduction of a matrix, you do not need to show all intermediate steps. Caveats:

- If you do not show intermediate steps, you may lose partial credits in case your answer is incorrect.

- If you do not show intermediate steps, then you must still show the matrix that you start with, and the matrix that you end up with.
