I've heard that there are 8 ways to solve system of linear equations.is it true ? If it is true what are they?
Welcome to the forum.
8 ? hhmm I can 'start the ball rolling' with
(i) simultaneous equations by elimination
(ii) simultaneous equations by substitution
(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.

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.
No great discovery was ever made without a bold guess.
