We want to solve this system of equations using the gauss -georgon elimination method.
00:15
So we need an augmented matrix 2, negative 2, negative 4.
00:21
Negative 3, 3, 6 are the coefficients, augmented with the constants, negative 2 and 3.
00:29
So we have to reduce, get this in a reduced row form.
00:37
So let's first take half of row 1.
00:41
Then it becomes 1, negative 1, negative 2, negative 1.
00:46
That's half of row 1.
00:52
Now we want to get a 0 below it.
00:54
So we could take row 2 and add 3 times row 1 and put that in row 2...
