To find two numbers that add up to 4 and multiply to -21, we can set up a system of equations. Let's call the two numbers x and y. We have the equations x + y = 4 and x * y = -21. By solving these equations simultaneously, we can find that the two numbers are 7 and -3. This is because 7 + (-3) = 4 and 7 * (-3) = -21.
