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

Live as if your were to die tomorrow, and learn as if you were to live forever. Love as if you've never been hurt, and dance as if no one's watching. Listen as if you have nothing to tell, and quote as if you know what you're saying.
