Question 87444
This is a strange question.  I think somebody is really stretching for this one, and I'm not sure exactly what they want.  Here is my thought:


Solving two equations and two unknowns is different from solving one equation and one unknown in that you must first eliminate one of the unknowns.


Solving two equations and two unknowns is the same as solving one equation and one unknown in that after you eliminate one of the unknowns, you must solve one equation and one unknown.
