Solving Systems of Linear Equations in Three Variables Using Determinants

Pi Mathematica | Math Simplified on Instagram: "Cramer’s Rule is a method in linear algebra used to solve a system of linear equations with the same number of equations as unknowns, provided the system has a unique solution. It works by expressing each variable as a ratio of determinants. For a system AX = b, where A is a square coefficient matrix and b is the constant vector, the solution for the i-th variable is given by det(A_i) / det(A). Here, det(A) is the determinant of the coefficient mat
