Hi! Whenever I try and solve a systems of equations such as the simple one above, an error like this one shows up, where it says that there was a problem using sym/solve and maplemex. This is a problem I've had since December and I have no idea how to fix it. I have the symbolic math toolbox installed, so that does not seem to be the issue. Any help would be greatly appreciated!

You accidentally installed the MATLAB Connector for Maple when you installed Maple. You need to go into your Maple installation directory and find the uninstaller for the connector.
Or you could remove the Maple stuff off of your MATLAB path using pathtool.
which -all syms
will probably show two directories, one of which involves the word 'maple': go into pathtool and find that directory in the list and click on it and click 'remove', then Save, then Close.

Hi Walter, I did install the Symbolic Toolbox at first, had the same errors, removed those folders, and reinstalled the toolbox. However, reinstalling the toolbox only brought the same maple directories back, and I would receive the same errors again. You said that using
which -all syms
would show two directories but it only shows one for me -- the one with "maple." I believe this is related to the fact that I do not have a toolbox/symbolics/symbolics path in my pathtool. Is there a way I can manually get that path?

I meet the same error, and I fix the problem just by clicking HOME -- Set Path -- Default.

I was not able to reproduce that error , do you have a valid license for it ?
license('test','symbolic_toolbox') % should return 1
It‘s better to contact Mathworks Support Team by clicking the Contact Us button on the top right corner of this page.

I checked and I do have the license for it, I'll try contacting the support team, thanks!
And I'm sorry, but what do you mean by there is a Maple shadowing? I've only been using Matlab on and off for a few months and am unfamiliar with a lot of terms.
