2) Matrices can be used to solve a set of simultaneous equations. If you have a set of
equations, you can represent these in the form AX=B, where A is a matrix of the
coefficients, X is your unknown variables and B is a vector of values on the right hand
side of the equation. You can solve for x using: x=A\B (note the left division). Look at
Gilat, sample problem 3-1, for how to get a set of simultaneous equations in AX=B form.

Here is a section from Lay, D.C. “Linear Algebra and its Applications”: What are A and b, and what is the result for x? Check the result using A*x.
