This decline disrupted the ecosystem. Following a study of the wolves’ impact, ecologists regarded wolves as the (a) keystone species of the ecosystem, as their absence caused a (b) domino effect on the ecosystem. The correct answer is A1 and B2.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
