The two numbers are -5, 3. Which are multiply together to equal -15 and add together equal -2.

Explanation:

Step:1

Let, X,Y.

Where X, Y are two numbers.

Step:2

Form the Multiplication equation from given,

X×Y=-15 (∵ Multiply to equal -15)

Step:3

Form Addition equation from given,

X+Y= -2 (∵ Add equal to -2)

Step:4

Check for alternatives to satisfy both equations

Assume, X=1, Y=-15

-15+1 = -14 (Not Satisfy addition equation)

1×(-15)= -15 (Satisfy multiplication equation)

Assume, X=15, Y=-1

-1+15= 14 (Not Satisfy addition equation)

(-1)×15= -15 (Satisfy multiplication equation)

similarly.,

assume X=-5, Y=3

-5+3= -2 (Satisfy addition equation)

(-5)×3= -15 (Satisfy multiplication equation)

So, the two numbers are -5,3.
