I'm not very familiar with C++, so I'll make only one suggestion: Try to never put logic into a header (.h or .hpp) file, use source (.cpp) files for that purpose. Try to leave header files only for declarations and macros. In fact, since #include is only text inclusion, you can include .cpp files too if you absolutely need to include logic and definitions. Although that's not common in small projects like this, in larger projects it's more common (thanks @Mast!).

Also, one more point, try not use using namespace std in your code, it might cause namespace collision among other bad things (see this SO post: Why is using namespace std considered bad practice). Try to use qualified names instead.

One more thing I found: EquationSystem.h and main.cpp have output in Spanish, while the others are in English. Has code been integrated from somewhere? Try not to have inconsistencies like this in code, especially in the UI.
