To find two numbers that multiply to 18 and add up to -6, we need to set up a system of equations. Let the two numbers be x and y. We have the equations xy = 18 and x + y = -6. By substituting y = -6 - x into the first equation, we get x(-6 - x) = 18. Simplifying this equation gives us x^2 + 6x - 18 = 0. Solving this quadratic equation, we find the two numbers to be -3 and -9.
