The following is the decoding matrix:

Use this to decode the following message.



After giving the decoded message, explain your steps on how you decoded this, and why the process works.

For an extra problem,
 * 1) Make up your own message.
 * 2) Make up your own decoding matrix.
 * 3) Write out the coded message you would give someone who had the decoding key.
 * 4) Give the answer. (the message you came up with...but show, mathematically using matrices, how to get it)
