We are given with the system of linear equation.
00:04
We have converted into matrix.
00:07
The left side terms of coefficient of x, y, z will be written here and that is 5, 17, 8.
00:17
Next is 2, 7, 5, 1, 3, minus 2 and this term that is on the right side or we can say that on the equal to side is written in there.
00:33
It's a 13, minus 5, 7.
00:37
Now this is called augmented matrix.
00:40
We have to check that the rank of this matrix equals to this augmented matrix or not.
00:46
If the rank is same that means it has a solution.
00:50
If it is not same that means it does not have solution.
00:53
We will use elementary operations that is r1.
00:57
R1 is changes with r3.
01:01
Change r1 with r3...
