Question

The solution set of x + y = 0, x, y eN is​

Answer 1

Step-by-step explanation:

what is the solution set of

x + y = 0

x - y + 2 = 0

-----

x + y = 0

x - y = -2

----

Add and solve for "x":

2x = -2

x = -1

-------

Solve for "y":

x + y = 0

-1 + y = 0

y = 1

-----

Solution: (-1,1)
