Cramer's rule for the solution of a system of equations in 2 variables
We recall from our earlier classes that a system of linear equation with two variables is given by This system of linear equation may have either one solution or infinitely many solutions or no solutio..

We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination method, Gauss-Jordan method e..
Consistency of a system of linear equation
The above discussion leads to find the solution of a system of linear equations in two variables by using Cramer's rule. Cramer's rule suggests the use of determinants to solve a system of linear equations. Let us denote a 1 b 2 - a 2 b 1 (Denominators of x and y in (4) and (5)) as the de..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Looking for More Help!
