<u>Given</u>:
Let the two numbers be x and y.
Two numbers multiply to be -7 and add to be -6.
This can be written in equation as,
and
<u>Value of the two numbers:</u>
Let us determine the value of the two numbers using substitution method.
Substituting 
in the equation , we get;
Simplifying, we get;
Thus, the values of x are x = 1,-7
When x = 1 , the equation becomes 
When x = -7, the equation becomes 
Therefore, the two numbers are 1 and -7
