The document outlines the Cramer's rule method for solving systems of linear equations in 6 steps. The method involves: 1) calculating the determinant of the coefficients, 2) rearranging columns to isolate one variable, 3) calculating the value of the determinant after inserting the constants, 4) repeating steps 1-3 with the coefficients inverted, and 5) summing the results of steps 3 and 4 to obtain the value of the isolated variable.
