2013-10: Solution Salvation

Many people have taken some sort of algebra class where you are presented with a set of linear equations like:

3x + 2y = 13

x - y = 1

The answer in this case is x=3 and y=2

Write code which solves this type of problem. Hint: this is the easiest of all of the problems presented here.

The first argument is a vector of the values for the equations and the second argument is a matrix of the coefficients.
