I'm confused why the answer is not (E).
From Statement (1):
q(r+s) = r +s
Therefore q = 1 or 0
From Statement (2):
We know (r+s) ≠ 0
Statements (1) + (2) - couldn't variable q still be 1 or 0?
Edit: Annnnnd, I just realized that q cannot be 0 because it were, statement (1) would not hold true. Too quick to post.
q=1 or r=-s; How are you calculating q=0? Had the equation been q(r+s)=0 then q=0, r=-s would have been the solution.
