To find two numbers that add to -18 and multiply to -162, we can set up a system of equations. Let's call the two numbers x and y. We have the equations x + y = -18 and xy = -162. By solving these equations simultaneously, we can find that the two numbers are -9 and 18. These numbers satisfy both conditions: they add up to -18 and multiply to -162.
The numbers are: 6 and -27
