Let us break the task into two parts: first, we find y such that. L y = b. Then,find x such that. U x = y. It is obvious by multiplying the last equation by L from the left that such x will be the solution to the original problem.

WebWe have learned how to solve a system of linear equations Ax = b by applying Gaussian elimination to the augmented matrix A~ = A b, and then performing back substitution on the resulting upper-triangular matrix. However, this approach is not practical if the right-hand side b of the system is changed, while A is not. WebThis method, characterized by step‐by‐step elimination of the variables, is called Gaussian elimination. Example 1: Solve this system: Multiplying the first equation by −3 and adding the result to the second equation eliminates the variable x: This final equation, −5 y = −5, immediately implies y = 1.
