------------------------
Substitution Method:
------------------------

1,)
--------------
X +3y = 11
2x - y = -6
-------------

Try x=11-3y
and substitute continuing with 2%2811-3y%29-y=-6.


2.)
--------------
x -2y = 5
X = 2y + 11
--------------

Most obvious, substitute for x, continuing with %282y%2B11%29-2y=5, ... and find what happens.
