Answer:
(k,0)
Step-by-step explanation:
\(x+y=k\)
\(x-y=k\)
To solve for x and y we add both equations
\(x+y=k\)
\(x-y=k\)
---------------------------
\(2x=2k\)
Divide both sides by 2
\(x=k\)
Now plug in k for x and find out y
\(x+y=k\)
\(k+y=k\)
Subtract k on both sides
\(y=0\)
Ordered pair is (x,y) that is (k,0)
