How can Bob decrypt the message?

Bob can take the encrypted message vector, split it into sub-vectors of three elements each, multiply each sub-vector by the inverse of the encryption matrix, then reassemble the resulting vectors into the original message.

Does Eve need to know the inverse matrix to decrypt the message?

What is the decrypted message corresponding to [ 2 23 3 ]?
