The system of neutral type difference equations with delays {?(x(n) + p(n) x(n - ?))= a(n) f(y(n - l)) ?y(n) = b(n) g(z(n - m)) ?z(n) = c(n) h(x(n - k)) is considered. The aim of this paper is to present sufficient conditions for the existence of nonoscillatory bounded positive solutions of the considered system with various (p(n)).
