System of linear equations can arise naturally from many real life examples. Generally speaking, those problems come up when there are two unknowns or variables to solve. In the figure above, there are two variables to solve and they are x and y. This kind of system is called system of ...
Addition of any row multiplied by a constant to another row Observation: Typically we apply the above transformations to the augmented matrix A|C. Definition 4: The Gaussian Elimination Method is a way of solving linear equations and is based on the transformations described in Property 9. Suppos...
Addition Method:The addition method, also known as the elimination method, involves adding together equations with the aim of eliminating one of the unknown variables from the resulting equation. This technique usually involves multiplying the equations with a constant to effectively e...
Example Problem 1: Solving a System of Linear Equations Using Elimination with Multiplication and Addition Solve the following linear system using elimination: 2x+y=54x−2y=14 Solution: Let's number the equations, so we may refer to them more easily in the solution:...
