Hello, I am revising and need help learning how to solve this for my cryptography class. Please help and thank you!

3. Consider the Hill Cipher with P = C = (Z26) and ek(x) = Kx where K = 9 13 2 3 Find the plaintext if the ciphertext is ESGWIL. 4. Decrypt the ciphertext TGEEMNELNNTDROEOAAHDOETCSHAEIRLM that was encrypted with the Permutation Cipher by using the key T= 1 2 3 4 5 6 7 8 4 1 6 2 7 3 8 5
