Bug in symbol math Prime 6

> What is it!

Its a question with a huuuuuge picture but without a worksheet 😞

OK, lets get serious - the bug you found is not considered a bug by PTC but rather a feature!

This feature is called "auto-labelling" and has nothing to do with old or new symbolics.

The "x" in the output of the symbolic evaluation are labelled "Variable" but when you typed "solve, x" this "x" gets labelled as "(-)", meaning "Automatic".

The symbol processor (both) treats them as different variables and obviously they can't find a solution for a variable which does not occur in the equation.

Solution is to manually label the variable you are looking for as "Variable" or change the label of the copied output of the symbolic eval as "Automatic" (which you can't do if you use is as in the following pic).

Its quite annoying to have to do so!
