Q is not equal to zero and k = (Q x n - s)/2.What is n?	Choose the most appropriate option.
A) (2 x k + s)/Q
B) (2 x s x k)/Q
C) (2 x k - s)/Q
D) (2 x k + s x Q)/Q
E) (k + s)/Q
k=(Q*n-s)/2   =&gt; (2k+s)/Q = n   (2 x k + s)/QNSWER:(2 x k + s)/Q
<result>A</result>
Q is not equal to zero and k = (Q x n - s)/2.What is n?
