How to solve the AES key scrambler

I hope this information helps some people who have trouble figuring out the AES key scrambler.

k = normal key
x = keyX
y = keyY
C = constant

let's algebra !!!!

let's start with
Code:
k = (((x <<< 2) ^ y) + C) <<< 87
Solve for k

Code:
k = (((x <<< 2) ^ y) + C) <<< 87
Solve for x

Code:
k        = (((x <<< 2) ^ y) + C) <<< 87
  >>> 87                         >>> 87
(k >>> 87)     = ((x <<< 2) ^ y) + C
           - C                   - C
((k >>> 87) - C)     = (x <<< 2) ^ y...
