Okay ShallBeTheLast, what we will do will involve a lot of simple plug and play kind of actions.

To start we must notice one number must be negative and the other should be positive, because the multiplied number is a negative.

Next, lets multiply number that have a sum of 10 (keep in mind one has to be negative and the other has to be positive).

-1 * 10 = - 10 false

-2 * 12 = - 24 false

-3 * 13 = - 39 false

notice that no number working and it's only getting farther away.

There is no solution for this that involves to integers.

I think you might of wrote the question backwards.

If that is the case we would run numbers like ...

-1 * (-6) = 7 false

-2 * (-5) = 10 true!

-2 and - 5 would work
