Question

What two numbers multiplied equal 6 but added together equal -7?

Answer 1

-6 and -1

Explanation:

let's suppose there are two numbers x and y so that it that works that would give the following equations

`x*y=6 \\ x+y =-7`

now let'S rewrite the first to the form y =

`y=(6)/(x)`

and plug that into the second one

`x+(x)/(6) = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6`

use that to find out what y is

`-6+y=-7|+6\\y=-1`

you can check that with the first equation
