Use an algorithm that you would systematically follow to apply
the technique and solve each set of systems of linear
equations.
For example, you may select the technique of finding the
inverse of the coefficient matrix A, and then applying Theorem
1.6.2: x = A^-1 b. There are several ways that we have learned to
find A^-1. Pick one of those ways to code or write as an
algorithm.
Or another example, you may select Cramer’s rule. Within
Cramer’s rule,...
