Answer:


-5\:\mathrm{and}\: 11

Explanation:

We can write the following system of equations:


\begin{cases}x+y=6\\x-y=16\\\end{cases}

Adding both equations together, we isolate
x and get:


2x=22,\: x=11

Plugging
x=11 in any of the equations, we can solve for
y:


11+y=6,\: y=-5

Verify that the solution pair
(11, -5) works
\checkmark

Therefore, the two numbers are
\fbox{$-5\:\mathrm{and}\: 11$}.
