Hello everyone.
00:01
So here, rewriting the given equation in augmented matrix we get, so we will get 336 minus 6 minus 6 minus 12, 0 minus 3 .9.
00:42
And here it will be 0 .00.
00:46
Now using row operation we will get r2.
00:50
So we'll replace r2 by r2 plus 2r1, that is equal to 336 -0 -0 -0 minus 3 -39 and it will be 0 -0.
01:08
Again, we will replace r2 by r3 and we will use r1, we will replace r1, r1 divided by 2.
01:29
If we divide this r1 with 2, we will get 1120 .0 minus 399 0000.
01:40
Now we will again use the operation r2.
01:44
We will replace r2 by r2 divided by minus 3.
01:49
112 01 minus 3 0000000.
01:53
Here it will be 0 0...
