To solve using matrices, you're usually given a set of 2 or more linear equations. Once you have that, isolate the variables and write numerically in the form of a matrix, dividing the right side from the left. Ex. : 2x + 3y = 7; 4x - y = 2 Isolating variables: [2 3 | 7]
[4 -1 | 2] From there onwards, it should be easy to solve.

How do you decide whether to use elimination or subsitution to solve a three-variable system?
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.
