Gaussian Elimination With 4 Variables Using Elementary Row Operations With Matrices
This precalculus video tutorial provides a basic introduction into the gaussian elimination with 4 variables using elementary row operations with 4x4 matrices. You need to convert the system of linear equations into an augmented matrix and write it row echelon form using matrix row operations. You can solve the system using back substitution.
