x + y = k
x - y = k
---------- Subtract
2y = 0
y = 0
x = k
==========
Intersection (k,0)

You can put this solution on YOUR website!
x + y = k
x - y = k
---------
2x + 0y = 2k

2x = 2k

x = 2k/2

x = k
----------------------------------------------------------------
x+y = k

k+y = k

y = k-k

y = 0

So the solutions are x = k and y = 0

So the lines intersect at (k, 0)
