What number, when you multiply it by 5 and add 6, then multiply that result by 4 and add 9, gives you a number that, when you multiply it by 5 and subtract 165, gives you a number that, when you knock off the last 2 digits, brings you back to your orignal number?

Any number.

5(4(5x+6)+9)-165=100x
5(20x+33)-165=100x
100x+165-165=100x
100x=100x
x=x
