Gaussian Elimination

I explained how to use Gaussian Elimination to solve a system of equations.

I think about exercise after the teaching would have helped reinforce what was learnt...
It was easy to follow through tho

Is it necessary to turn the lowest left number to zero first? Or I can turn the center left most number first if I want to?

Hey for the first 0 I simply did R1-R3. But when I got the finished matrix it was -13z=22 which I think is wrong. So is it that you shouldn’t simply subtract 2 diff rows or something

me watching this the night before my exam 😂, this was explained better than my teacher

Kramer’s rule works faster and is easier for larger sets of equations.
