#Cramer's #Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables. Consider a system of two linear equations in two variables.
•Step1: Form a matrix of the coefficient of the unknown variables and find the determinant of the matrix formed.
•Step2: Find the determinant of the matrix with respect to x by replacing the x column with the constant column.
Step3: Find the determinant of the matrix with respect to y by replacing the y column with the constant column.

To solve for x, divide the determinant with respect to x by the main determinant.

To solve for y, divide the determinant with respect to y by the main determinant
