C i p h e r ≡ m ⋅ M e s s a g e or C i p h e r ≡ m ⋅ M e s s a g e + s. 🔗 Solving these for the ciphertext we got the equations: M essage = m−1Cipher or M essage = m−1Cipher+(−m−1s).

The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse. gps wild about hunting medium range bag
