Decrypt the message BNW MVX WNH if it was encrypted using a cypher shift with a shift
9 mapping

SEND MONEY

Step-by-step explanation:

A cypher shift encrypts a message by shifting each letter a certain number of places.

For example, N is the 14th letter of the alphabet.

If we shift 9 places to the left, we get the 5th letter of the alphabet, which is E.

Or, if we shift 9 places to the right, we get the 23rd letter of the alphabet, which is W.

Assuming the shift is to the left:

B = 2

2 − 9 = -7

-7 + 26 = 19

19 = S

N = 14

14 − 9 = 5

5 = E

W = 23

23 − 9 = 14

14 = N

M = 13

13 − 9 = 4

4 = D

V = 22

22 − 9 = 13

13 = M

X = 24

24 − 9 = 15

15 = O

W = N

N = E

H = 8

8 − 9 = -1

-1 + 26 = 25

25 = Y

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
