what are two numbers that have a sum of -8 and a difference of 4?

Answer 1

x+y=-8

x-y=4

By adding the two equations together, we get:

2x=-4

Dividing each side of the equation by 2:

x=-2

Now, substitute -2 into the first equation for x, we get:

(-2) + y = -8

add 2 to each side of the equation:

2 -2 +y = -8 +2

simplify:

y=-6

Final Answer: x=-2, and Y=-6

You can check the answer by going to the original questions:

Sum = -2 + (-6) = -8 (CHECK!)

Difference = -2 - (-6) = -2 +6 = 4 (CHECK!)
