In the lecture on Cramer's Rule, Dr. Eaton begins with the case of a system of two equations in two variables and how to find the determinant of the denominator as well as the determinants of the numerators. Next, in the case of a system of three equations in three variables, Dr. Eaton again shows how to find the determinant of the denominator as well as the determinants of the numerators. Examples accompany each of the cases as well as four complete examples at the end to make sure you understand all concepts.
