Explanation:

I took a test EXACTLY like this a very long time ago, and since they look similar all the way down, passed down from generation to generation, this would be the obvious answer.

I am joyous to assist you anytime.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.

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.
