No, Gaussian elimination can be used with any matrix or any system of equations.

Gaussian elimination is basically applying the same steps to the matrix that you would to solve a system of equations- in fact, Gaussian elimination was first applied to systems of equations rather than matrices.

Yes. In fact, I gave it. Did you notice that my answer had two paragraps? First paragraphs answers first question. Second paragraph answers second question.
