RREF stands for Reduced Row Echelon Form which means you could get a matrix that looks like where the left 3 columns is I, the identity matrix, and the last .column is your solution. RREF can also be used for inconsistent systems and consistent dependent systems, unlike using Cramer’s Rule or using inverse matrices to solve the equation where ...
