Secret messages can be encoded by using a code and an encoding matrix. If we have the code: and an encoding matrix E, we can encode a message by taking every two letters of the message, converting them to their corresponding numbers, creating a 2 × 1 matrix, and then multiplying each two numbers by E. The message may be unscrambled with a decoding matrix which is the inverse of the coding matrix, E-1. Determine if the given pair of encoding matrices are inverses of each

other. and
