I've heard that there are 8 ways to solve system of linear equations.is it true ? If it is true what are they?

Re: System of linear equations
hi Sabbir,
Welcome to the forum.
8 ? hhmm I can 'start the ball rolling' with
(i) simultaneous equations by elimination
(ii) simultaneous equations by substitution
(iii) matrices
(iv) graph (not really suitable beyond 2 unknowns)
(v) spot the answer by inspection and check it works
...........................
Now I've run out for the moment.
Hopefully others can carry on.

Re: System of linear equations
Hi Sabbir;
There are probably more ways than that. Determinants, iteration,over relaxation, sor, Newton - Jacobi are a few more.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
