🔷10a - Gaussian Elimination and Row Echelon Form - Example 1

[@smartdean8910]

Thanks 😊. Can I use this method to solve for linear dependence/independence ??

[@SkanCityAcademy_SirJohn]

You can, but it's best to use Gauss Jordan method. So that you can clearly see whether each row or column is a linear combination of another or not.

I have a question on the elementary row operation uh aren’t you supposed to be change the the row operations for example the first operation r2 becomes 2r2-r1? Coz this changes the signs

[@SkanCityAcademy_SirJohn]

Well 2*R2 - R1 for the first column is 0 which is what we want. I did, R1 - 2*R2 , that will also give 0, so there is no big deal, both are correct.
