Solving linear equations. [Discuss]

Hey, Iv a question. I was recently asked to discuss (in less then 100 words!) the differences between Gaussian Elimination, Cramer's Rule and the Inverse Method for solving a system of linear equations. Its a style question iv never came across before, so I was fairly stumped. I was told afterwards what the most important…

Hey,

Iv a question. I was recently asked to discuss (in less then 100 words!) the differences between Gaussian Elimination, Cramer's Rule and the Inverse Method for solving a system of linear equations. Its a style question iv never came across before, so I was fairly stumped.

I was told afterwards what the most important thing was making sure the system wasnt equal to zero - that was the "key" part of the answer. Wat was being looked for apparently was, while they all do the same thing - one is better then another for various reasons.

Question is, what reasons? What should I have said? Any ideas?

Thanks.
