Kramer’s Rule is a mathematical method used to solve systems of linear equations. It provides a way to find the values of variables by using determinants from matrices. This rule is particularly useful when dealing with three equations and three unknowns, allowing for a straightforward calculation of each variable. To apply Kramer’s Rule, one must first express the system of equations in matrix form. Then, the determinant of the coefficient matrix is calculated, along with the determinants of matrices formed by replacing one column with the constants from the equations. The values of the variables are found by dividing these determinants.
