Help me with the Cryptography and Codes questions.

7. A shift key is exchanged using the Diffie-Hellman method with primitive root g = 5 modulo the prime p = 47. The actual numbers exchanged over a public channel were X = 38 and Y = 3. Find the shift key k, and use it to decipher the message EQPITCVWNCVKQPU. (The above was obtained by shifting & steps forward in the circle A > B C . . . Z ) A)
