I have a problem. I was waiting -5/7 for x and -22/7 for y but I obtained decimal of the divisions and not the fractions in solver app or linsolver app. I have choosed "EXACT" in CAS, but no fractions only decimal number.

Certainely I miss configuration, but how to have result in form of fractions ?

The Solver and Linear Solver apps are numeric solvers, not symbolic solvers. In other words, they are like Home operations, not CAS operations. Whenever you want exact (symbolic, algebraic) results, use the CAS.
