The value of x-y is negative, and x and y are both positive. what can you conclude about the values of x and

If both the values of x and y is together positive and also at the same time negative then it probably would indicate that the values consisting x and y are in direct proportionality or in a positive correlation with one another. The values simultaneously increases and decreases at the same time.
 Consider x = y or –x = -y.
These equations mean that above explained phenomenon between these two occurring unknowns.
