I have been using a nice TeX package called **spaling **for some years now. I use it a lot for systems of equations and matrices. I am assuming we cannot use packages like that in the TeX in moodle's XML. So I am wondering how we can do systems of equations in moodlesformulas (with randomized variables etc) so that they come out looking nice like:

where entries are aligned. I will experiment with HTML tables again, but I was just wondering:

(1) is it possible to introduce TeX packages in moodlesformulas?

(2) is there a nice way to write systems of equations in moodlesformulas?

Any help would be greatly appreciated!
