    The strip  -10 < x + y < 10  between the red and the green lines, and

    the strip  5 < x < 10  between the blue and the magenta lines.


The set of solutions to the given inequalities is the area of the parallelogram (between the four lines) 
which you see in the figure (the interior area of the parallelogram).


The solution points can be located above, on and/or below the horizontal straight line y = -15.


So the answer to the problem's question is 


          "the relationship cannot be determined by the information given."
