1. Many free software mathematics packages on the Internet will solve a system of equations given the coefficients in the system.
Problem: find out which of the four techniques (the Method of Addition, the Method of Substitution, Gauss-Jordan Elimination, and Cramer's Rule) is used in the majority of these types of software packages. Give your opinion why this technique is the one most commonly used. I am not sure about this one.
