tarde ,lo que se pide es que resuelva sistemas de ecuaciones lineales
y que las soluciones puedan ser una negativa o dos positvas o dos negativas
http://www.vadenumeros.es/tercero/sistemas-de-ecuaciones.htm
Y claro está tienen dos incógnitas x e y,que llegan hasta 19 , aunque se pued kmbiar
Y aquí va la solución
Código:
