To find two numbers that multiply to 70 and add up to -12, we can set up a system of equations. Let's call the two numbers x and y. We have the equations xy = 70 and x + y = -12. By factoring 70 into its prime factors (2, 5, and 7), we can see that the two numbers are -10 and -2. Therefore, -10 * -2 = 70 and -10 + (-2) = -12.
