Gauss elimination and back substitution
WebGaussian elimination is a method of solving a system of linear equations. First, the system is written in "augmented" matrix form. Then, legal row operations are used to transform … WebWe now formally describe the Gaussian elimination procedure. Start with matrix A and produce matrix B in upper-triangular form which is row-equivalent to A.If A is the augmented matrix of a system of linear equations, then applying back substitution to B determines the solution to the system. It is also possible that there is no solution to the system, and the …

WebBack‐substitution into the first row (that is, into the equation that represents the first row) yields x = 2 and, therefore, the solution to the system: (x, y) = (2, 1). Gaussian elimination can be summarized as …
WebGaussian elimination is the name of the method we use to perform the three types of matrix row operations on an augmented matrix coming from a linear system of equations in order to find the solutions for such system. This technique is also called row reduction and it consists of two stages: Forward elimination and back substitution. WebIn this form, the equivalent linear system can easily be solved using back substitution. This process is called Gaussian elimination Steps used to obtain an equivalent linear system in upper triangular form so that it can be solved using back substitution., named in honor of Carl Friedrich Gauss (1777–1855).
