Yeah...q is basically the difference between p and r. Statement 2 tells you exactly what that is.
It must have been love...but it's over now!

Statement 2 gives you p - r = 31

and the question stem is q = r - p

You can get the answer from this? Thanks.

If p + q = r, what is the value of q?
(1) p = 31
(2) r + 31 = p

Given p+q=r which means q=r-p

r+31=p which means r-p=-31

So q = -31

I guess you moved 'r' in the opposite direction. Even if you did so and p-r=31, multiply with -1 on both sides to get r-p=-31.
