In your post, you missed to determine "x" and "y".


Be sure that I can guess what the "x" and "y" are, but I do not want to base my solution on my guessing.

Assume that neither A nor B is zero (since that will make the expression x%2FA+%2B+y%2FB invalid).
Then the problem implies that the point (A,B) is the midpoint of the segment intercepted between the coordinate axes.
It follows then that the y-intercept of the line is (0,2B) and the x-intercept is (2A,0), and the line itself will have the intercept form given by

x%2F%282A%29+%2B+y%2F%282B%29+=+1,

which implies that

x%2FA+%2B+y%2FB+=+2.

Therefore the value of x%2FA+%2B+y%2FB is highlight%282%29.
