That allows me to essentially take the integral above the new y' and simply multiply it by 2.

Rather than going through the trouble of transforming it, I just subtracted the integral of y=x, as that's the symmetry line.
I got 0.536595 for the area -- found the second intercept at .95012, then just took the integral from 0 to .95012 of [10*ln(x)/exp(x)-x] and multiplied by 2.
