WebFigure 1: Linear systems in two variables. If the lines intersect, as depicted in Figure1a, the point (x;y) where they intersect is a solution to both of our equations, and thus a solution to the system of linear equations. Moreover, the lines can’t intersect at any other points, so this is the unique solution to our system.

WebGaussian Elimination, LU-Factorization, and Cholesky Factorization 3.1 Gaussian Elimination and LU-Factorization Let A beann×n matrix, let b ∈ Rn beann-dimensional vector and assume that A is invertible. Our goal is to solve the system Ax = b.SinceA is assumed to be invertible, we know that this system has a unique solution, x = A−1b.
