please help explain!!! please explain. how i can use the following matrix to decode these crytograms and how i can encode my response to cryptogram 2.

we have to decode the cryptograms that reveal messages but than respond in a cryptogram for someone else to decode. please explain all, i do not understand

Cryptogram 1: -67 16 33 -19 5 7 Cryptogram 2: -59 7 37 17 2 -20 -131 31 75 -72 21 33 48 18 21 -83 22 41 7 2 -10 28 -20 -8 19 -18 -2 -19 7 7 12 -16 3 4 -12 12 22 -19 -3 Your response to Cryptogram 2 (ENCODED!): 0= A cryptogram is a message written in secret code. Matrix multiplication can be used to encode and decode messages. For our purposes, we will use the following code for our messages: 6=F 12=L 18 = R 24 = X 1 = A 7= G 13 =M 19=S 25 = Y 2 =B 8=H 14 =N 26 = Z 3-C 9= I 15 = 0 4=D 10 = J 16 =P 5 = E 11 = K 17 = Q 23 =W 0 A cryptogram is a message written in secret code. Matrix multiplication can be used to encode and decode messages. For our purposes, we will use the following code for our messages: 6-F 12=L 18=R 24-X 1 = A 7=G 13 = M 19=S 25-Y 2=B 8= H 14=N 20=T 26-Z 3=C 9-1 150 21=U 4=D 10=J 16 =P 22 = V 5=E 11=K 17= 23 =W In order to decode our message, first you must find A, then multiply your code 3 pieces at a time for a 3x3 matrix and 2 at a time for a 2x2 matrix in order to get the numbers that correspond to our letters above.

The first cryptogram will provide you with the name of one of the great fathers of coding and cryptanalysis. In the second cryptogram, I will be asking you a particular question. Please encode your response back for ME to decode. Good luck! 1 -1 0 A= O -1 |-6 2 3 Cryptogram 1: -67 16 33 -19 5 7 Cryptogram 2: -59 7 37 17 2 -20 -131 31 75 -72 21 33 -48 18 21 -83 22 41 7 2 -10 28 -20 -8 19 -18 -2 -19 7 7 12 -16 3 -4 -12 12 22 -19 -3 Your response to Cryptogram 2 (ENCODED!)
