In this lecture, you'll learn how to apply determinants in order to solve systems of equations. The rule we're going to use is called Cramer's rule. Using Cramer's rule, we can solve systems of equations with both two variables and three variables by using only determinants. There is no graphing or algebraic work involved. The examples will help you understand this matter a little better. Cramers rule indicates situations in which a system does not have a unique solution. It does not specify whether the system has no solution or an infinite number of solutions
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
