Interesting, too, that solve(-x-e^x=0,x) with only one variable still results in the error message "Unable to isolate", but solve(-x-e^x=0,x=-.2) works!

I first get a warning when I enter solve (-x -e ^ x = 0, x) but press the ENTER key gives me the correct answer. When entering the value of the approximation -2 for x the First does not give me the warning but it gives me the correct value at one time but not in the format of the list as in the first case. See screenshots.

Note: I did it on the Virtual Calculator on PC with 11226 version.
