I see. You're trying to "Balance" the equation to a solution.
Heh, I had a hard time Bending my mind around "Ok, If I subtract a Number on One side, If got to both Add and Subtract it on the other... Or something like that! ".

Are you EXPECTED to do it this way? or can you just give the solution from any method you like.

BTW, How do you "Balance" the following and get the ranges of x?

|x^2 - 30*x + 9| < 7

I think finding the 2 sets of Hot Spots for x, or the 2 sets of roots for the eq's x^2 - 30*x + 2 = 0, and x^2 - 30*x + 16 = 0
is easier.
