Cramer's Rule

  • Cramer’s rule allows us to solve a system of equations using only determinants. There is no graphing or algebraic work involved.

  • Cramer’s 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.
