Cramer's Rule Solved Example - (3×3) matrix

This video lecture is useful for all the students... I have try to providing quality content with out any charge, especially to those students who cannot afford fees to pay. 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. A determinant is a real number that can be very useful in mathematics because it has multiple applications, such as calculating area, volume, and other quantities. Here, we will use determinants to reveal whether a matrix is invertible by using the entries of a square matrix to determine whether there is a solution to the system of equations. #maths #cramersrule #sets #determinants
