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.

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

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?

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

[AbubakarWan]

Please where did you get the 2 operation

[rnatoit]

how can i do this one?
3x-2y=z
6x+2z+6y=2
-x+y+3z=1
