x+7y=6 or
x=6-7Y
-(x=5-7y) subtract
----------------
0=1+0 no unique solutions.
Graphing:
7y=-x+6
y=-x/7+6/7 (red line)
-7y=x-6
y=x/-7-6/-7
y=-x/7+6/7 (green line)
2 identical equations with 2 unknowns.
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -x +6/7 and -x/7 +6/7).
