Problem with $2-$letter units in an affine encryption system. All these problems can be solved by hand.

All arithmetic is performed in $Z_{26}.x$ below is a $21$ matrix, as is $,$ while $$ is a $22$ matrix.

Encryption function: $f_E(x)=x+mod26$

In this problem, neither $$ nor $$ are known to us but we made an attack on this cryptosystem and discovered that the plaintext 'MONKEY' is encrypted as 'QIWFOC'. That is$,$

MONKEY $f_E$ QIWFOC.

Decrypt 'QCEWLY' in this affine system. QCEWLY $f_D$

$($input a $6-$letter string as your answer: $2+2+2)$THE ANSWER IS NOT 'OMEGAR' STOP COPY AND PASTING THE SOLUTION AS THIS PLEASE HANDWRITTEN ONLY OR PROPER WORKINGS NOT AI GENERATED
