The 3 methods used in solving a system of equations is : substitution, elimination, and matrices.

which method do I prefer ... depends on the equations.

if they are : x + y = 2 ... and x - y = 4 ... then I prefer elimination ... because u can just add them eliminating the y.

but if it is like : y = 2x and x + y = 4 ... then I prefer substitution.

I am not good at matrices ... so I dont usually use them ... but I believe they are pretty similar to elimination ... and shorter. Elimination takes many steps and if u mess up on a beginning step, it carries through to the end.
