How are human beings and chimpanzees phylogenetically related?

I would say that its they are descendant of a common ancestor. DNA shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago.

Explanation:

not sure but try c two haploid cells

explanation:

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.
