Solving-Linear-System-Of Equations-Using-Determinants

This resource is prepared for 'A,' level students and is a valuable lesson on solving systems of linear equations in 3 variables using determinants. In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution. It expresses the solution in terms of the determinants of the (square) coefficient matrix and of matrices obtained from it by replacing one column by the vector of right hand sides of the equations.
