Question

Which 2 numbers multiply to 36 and add up to -15?

Answer 1

Let the numbers be: x and y

Now, we will set up the equation with the variables and given info..

`x * y = 36 \\ x + y = - 15`

Solve using the substitution method

`x * y = 36 \\ x = - 15 - y`

`( - 15 - y)* y = 36`

`y = - 12`

`x = - 15 - ( - 12)`

`x = - 3`

➪ Therefore, The two numbers are: -12 and -3
