Affine Cipher Homework Below you will find examples of Affine Cipher equations. For an equation to be valid all the numbers created by the E(X) must be unique number and between 0 and 25. Also, x = D(y) and always be unique. Check which Affine Cipher equations are VALID. Explain why or why not. 1) Are the following equations below valid? (YES / NO) Why? E(X)= 19 x + 13 (mod 26) D(y) = 11 (y-13) (mod 26) following equations below valid? (YES / NO) Why
