Answer:
-6,13

Explanation:

Given

The sum of the two numbers is 20

and the difference of the two is -6

Suppose, the numbers are x and y


\therefore x+y=20\quad \ldots(i)\\\Rightarrow x-y=-6\quad \ldots(ii)\\\text{Solving} (i)\ \text{and}\ (ii)\ \text{we get}


\Rightarrow 2x=14\\\Rightarrow x=7


\therefore y=13

Therefore, the numbers are
-6,\ \text{and}\ 13
