Hello to everyone.
I was trying to make a program with my calculator, and I need to solve a system of equations. However, I don't have any results if I only do the solve command. Does exist any solution to this problem?

One possible solution is to make sure that your system of equations is defined correctly and that you are using the correct syntax for the solver. If you are using a programming language or calculator with a solver function, make sure that the equations are entered correctly (e.g. as a matrix or as a set of equalities) and that any necessary variables are defined.
