Answer:

-6 and -1

Step-by-step explanation:

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

[tex]x*y=6 \\ x+y =-7[/tex]

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

[tex]y=\frac{6}{x}[/tex]

and plug that into the second one

[tex]x+\frac{x}{6} = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6[/tex]

use that to find out what y is

[tex]-6+y=-7|+6\\y=-1[/tex]

you can check that with the first equation
