If you want a numerical answer, you can use find_root:
find_root(log(x^2)+%e^x+3=-x, x, 0.1, 1) -> .1196296556538211
I found the limits by plotting the function log(x^2)+%e^x+3+x and
noticing that there is a root near 0.1. Since this function is
monotonic for x > 0, it's also the only root. I leave it as an
exercise to find the other real root.
