what is the answer of
x-2y=-2
x-2y=3
----
Do you see that the two equations
cannot both be true? The pair of
equations is a contradiction and
has no solution.
-----
Mathematically you would subtract
the lower from the upper equation
and get:
0 = -5
========
That shows you mathematically that the
pair is a contradiction.
