I am trying to learn about equations and HP Prime's possibilities in solving equations. Now on my Home screen using solve() function does not give me any solutions, just X. For instance taking the simple example from the solve() Help:
solve(X-3=1) -> X
Same happens with all other equations.
What is going on?

I am using Textbook entry method.

solve() is meant to be run in CAS mode which is why it's in lowercase. In general, when you see a lowercase command or function, run it in CAS mode.
