We consider the scalar case and a a problem with systems of equations. In the scalar case, we work with the conditions of Neumann and Dirichlet. In the problem involving system, we consider the condition og Dirichlet. In order to get the results we use the theory of Leray-Schauder degree and a priori estimates. / Neste trabalho apresentamos resultados do tipo Ambrosseti-Prodi para problemas quasilineares envolvendo o aperador p-Laplaciano. Considerando o caso escalar eu um problema com sistemas de equações. Para os casos escalares, trabalhamos com a condições de Neumann e Dirichlet, já para o problema envolvendo sistema, consideramos a condição Dirichlet. Para obter mais resultados usamos a teoria do grau de Leray-Schauder e estimativas a priori.
