To solve the system of equations using gauss jordan elimination.
00:04
That means we need to create a matrix which contains the coefficients in front of x and y in the right -hand sides.
00:12
From the first equation we'll get 2, negative 1, negative 11, from the second equation will get 1, 06.
00:22
This is the system or the matrix of coefficients, the augmented matrix of coefficients in the right -hand side.
00:31
What we'll do now is we'll interchange the first and the second rows.
00:37
We'll get 1 -06 and 2, negative 1, negative 11.
00:43
Next we'll multiply the first row by negative 2 and add it to the second row.
00:52
So we'll get 1, 06, and in the second row we'll get 1 times negative 2 plus 2 is going to be 0...
