Answer:
(p-q) / (p+q) = 2/3
3 (p-q) = 2 (p+q)
3p - 3q = 2p + 2q
5p = 5q
p = q
This doesn't really help us very much! But really the principle that we are hoping to explain in the explanation is that if we have the following:
x/y = 2/3
We cannot say that:
x = 2 and y = 3
because we could have the following:
x = 6, y = 9
x/y = 2/3
6/9 = 2/3
2/3 = 2/3
This works as well. If you chose D based on trying to solve the equation, then that works perfectly fine as well.
