The Gaussian Elimination method - Matrices

Gauss elimination method is used to solve a system of linear equations. Let’s recall the definition of these systems of equations. A system of linear equations is a group of linear equations with various unknown factors. As we know, unknown factors exist in multiple equations. Solving a system involves finding the value for the unknown factors to verify all the equations that make up the system.

[@HashemAljifri515]

Sır is it necessary to make the first row corners 1?

[@AbubakarWan]

Please where did you get the 2 operation

[@kennethabwao4410]

Making it understandable. Thumbs up👍

[@iqinitiative]

Cheers mate 👍

[@Salamanca-joro]

12:48 why is the operation R2:1/-2 ×r2
In the first exam we said 1/3 not 1/-2
How can that happen ? Can we change the operation when ever we want?

[@tshiamomonyatsi234]

Does the diagonal numbers always have to be equal to one? Because from what I understand is that we are eliminated the number of unknown variables to a point where we can easily solve the variables by backward substitution

[@iqinitiative]

No. They don't always have to be ones. You can use other numbers as well as long the you maintain the zeros and then you use backward substitution.

[@Maths103]

Good explanation 🙏🤝

[@iqinitiative]

Glad it was helpful

[@emryd5567]

thank you for this

[@iqinitiative]

[@nazarenojamryan7673]

4:24 why 2x1 =0?

[@iqinitiative]

It's an operation 2(1) - 2 = 0

[@nazarenojamryan7673]

thankyou

[@benjaminmaurice9740]

​@@iqinitiativei don't understand, where'd the second 2 come from NJ

[@kazadichiputa]

Well explained 🔥🔥👏👏👏

[@iqinitiative]

I'm glad it was helpful 😊
