Bugs in Solve command.

[math7]

Hi, thanks for your reply Parisse. With the first equation yes it is correct now, after deleting the contents that had the variable "x" with the purge (x) command several problems were corrected. The first equation does give me both correct answers with the default settings. However with the second equation gives me an error message that says "Unable to isolate x in -x-e ^ x", how did you get the answers x = [- 0.56714329041, a]? With what CAS settings did you get the correct answer? Thank you very much.
