The sum of the two numbers = -12.6
The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4
Let x represent the first negative number
Let y represent the second negative number
x + y = -12.6
To make the above equation to be true, assume a value f x that is negative but greater than -12.6
Let x = -8.6
Substitute x = -8.6 into the equation x + y = -12.6
-8.6 + y = -12.6
Add 8.6 to both sides of the equation
-8.6 + 8.6 + y = -12.6 + 8.6
y = -4
As a proof:
-8.6 - 4 = -12.6
The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4
