Ești super ! ❤ Mă bucur că pot să învăț la mate fără să cheltuiesc bani la meditați

If we replace(test in the end) in ecuation this won''t work((3+(-1)+(-1))=3 with x=3 y=-1 z=-1 what means that the result its not correct..the correct answer is x=1 y=1 z=1

Because you replace the solution from second system to the first one. In this video I resolved 2 exercices. So pay attention!!!
