Cramer's Rule provides a method to solve systems of linear equations. It uses determinants to find the values of the variables by taking the ratio of the determinant of the original matrix to the determinant of the matrix with one column replaced by the constants on the right-hand side of the equations. The document provides an example of using Cramer's Rule to solve a system of 2 equations with 2 unknowns.
