Flap question

Alice $(A)$ and Bob$(B)$ use ElGamal encryption system with public key parameters: $q=23,g=5,$ Alice chooses the secret key, $x_A=10.$ Bob chooses the random integer $k=6,$ and wants to encrypt the message $m=14.$ Compute $C=(C_1,C_2).$ Note: $1.$ To be fully graded, provide a detailed solution with all computations included. $2.$ Feel free to make assumptions for any necessary values not explicitly provided in the question.

Note: provide a handwritten, detailed solution with all computations
