-8 and +7
Well first think this... There's going to be a negative and a positive factor. (+)*(-)=(-) We know that the positive is going to be bigger because the 12 is not negative. The only factors that make 8 are 2*4=8 and 1*8=8. So it isn't possible to multiply -8 and add to 12.
Well, isn't that just a happy little math problem! Let's think about it together. If we call the number x, we can create two equations: 8x + 12 = 2x + 120. By solving this, we find that x equals 9. So, the number you're thinking of is 9. Happy calculating!
6 and 2

They are -2 and -4

A negative and a positive number will multiply to a negative number. Other than that, -9 and -8 will satisfy your conditions.
