To decipher a code with the enciphering matrix known, rewrite the code in number form and produce column matrices. Then with the enciphering matrix, find its determinant and then the reciprocal modulo 26 of that number. For example, consider the enciphering matrix 4 1 3 2 which has a determinant of 5. This has a reciprocal modulo 26 value of 21.

How do I find inverses (2x2 only) and solve matrix equations? Standard: MGSE9-12.N.VM.10. Understand that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1 in the real numbers. The determinant of a square matrix is a nonzero if and only if the matrix has a multiplicative inverse
