(A) -3
(B) -1/2
(C) 0
(D) 1/2
(E) 3/2

­In GMAT we can solve any question in many  ways, but think the best possible way. we can solve with out using pen or solving all equations.

if we take 2 common in first equations , then it will be 2x(x+1/2)=0
so as per question x+1/2=0 then only both equations can be zero. so x=-1/2 ­
