How might an organism, that cultivates it’s own food production using a symbiotic fungi, benefit the fungi?

answer; the above statement is (true);

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.
