System of linear equations

I've heard that there are 8 ways to solve system of linear 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.  smile

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.

If it ain't broke, fix it until it is.
