Question

Given matrix $A = \begin{bmatrix} 1 \\ 1 \end{bmatrix} \begin{bmatrix} 2 \\ 3 \end{bmatrix}$ and the encrypted message matrix $M = \begin{bmatrix} 32 & 20 \\ 37 & 21 \end{bmatrix}$, find the secret message. Decoding Information - Use the following coding system to decode your final message: A=1 B=2 C=3 D=4 E=5 F=6 G=7 H=8 I=9 J=10 K=11 L=12 M=13 N=14 O=15 P=16 Q=17 R=18 S=19 T=20 U=21 V=22 W=23 X=24 Y=25 Z=26 and ANY SPACE will count as a "0".

Step 1

The given matrix A is [[1, 2], [1, 3]]. To find the inverse of a 2x2 matrix, we use the formula: A^(-1) = (1/det(A)) * [[d, -b], [-c, a]] where det(A) = ad - bc, and in our case, a = 1, b = 2, c = 1, and d = 3. Show more…
