Solving the system of linear equations
WebMay 1, 2024 · A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently. See Example 11.1.1. WebNov 24, 2013 · The best way to solve a system of linear equations of the form Ax = b is to do the following. decompose A into the format A = M1 * M2 (where M1 and M2 are triangular) Solve M1 * y = b for y using back substitution. Solve M2 * x = y for x using back substitution. For square matrices, step 1 would use LU Decomposition.
