4º item - o método da adição é um método de resolução de sistema de equações que pode ser aplicado
diretamente em sistemas que possuem em suas equações termos semelhantes opostos, como neste sistema:
s2x + y = 1
12x - y = 3
. realizando a subtração y - x com os valores das variáveis que solucionam este sistema,
obteremos como resultado:
(a)-2
(b) 2
(c) 0
(d) 1
