One method of solving a linear system AX = B with square coefficient matrix A when the solution exists is by using determinants and this is known as Cramer's Rule.This paper presents the Extended Cramer's formula of solving a linear system AX = B when the coefficient matrix A is an m × n matrix with n = m + 1 as an alternate process of elimination method.
