S2008 notes on problems 3.1-4,18,26
=======================================

3.1-4
=====
The answer "x=5, y=4" is the unique solution, as reported by the book.
Submitted work is expected to display the solution details, which
include documented toolkit steps of swap, combo, mult. Please do not
display arithmetic steps. Preferred is a frame sequence which ends with
last frame x=5, y=4.


3.1-18
======
The book reports "No Solution" which is correct. Display a frame
sequence with documented toolkit steps swap, combo, mult, ending in a
last frame that contains a signal equation "0=1" followed by the
statement "No Solution" or "Inconsistent."


3.1-26
======
The constants are A=23, B=21 in the formula y=A exp911x)+B exp(-11x).
Follow 3.1 Example 8.
