What 2 numbers can be multiplied to get - 4 but when added equals 3?

4 and - 1

Step-by-step explanation:

Solving for two variables can be done by setting up a system of equations. In this case you have two numbers 'x' and 'y' when multiplied is - 4:

x*y = - 4

When the same two number are added together it's 3:

x + y = 3

Using the second equation to solve for 'x', you can then use that expression to substitute for 'x' in the first equation:

x = 3 - y

y (3 - y) = - 4 or 3y - y² = - 4 or y² - 3y = - 4

Factor: (y - 4) (y + 1)

Solve for y: y = 4 or - 1

If y = 4, then x = - 1 or when y = - 1, x = 4, so the two numbers are 4 and - 1:

(4) (-1) = 4 and 4 + - 1 = 3
