Abstract

The work of Gabriel Cramer (1704-1752) that yielded the formula for solving an arbitrary number of unknown in a square linear system of equations has witnessed in the recent past, several methods of proofs regardless of the supposed high computational cost. It is our purpose in this research to proffer an alternative method of proof to Cramer’s formula for solving square linear system of equations
