Cramer's Rule (MATHEMATICS N4)

Cramer's rule is a good and effective or rather quick way to solve equations with more than one variables, for example it can be easy for a student to solve two equations with two unknown variables using simultaneous equations, but it won't be easy to solve three equation of three variables using the same method. Now the easy way to solve equations with many variable is using cramer's rule, so the video is to help students on how to perform calculations using this rule.
