Hello everyone, welcome to this video.
00:03
Now let us solve this equation using gauss elimination method.
00:08
So let us take this as equation number 1 and this as equation number 2 and this is equation number 3.
00:15
By solving 1 and 2 we get x1 minus 3 x2 minus 2 x3 equal to 0.
00:25
Here we have minus x1 plus 2 x2 plus x3 equal to 0.
00:33
So here we get on canceling the common terms we get x2 minus x2 minus x3 equal to 0.
00:47
Now taking the third equation which is 2 x1 plus 4 x2 plus 6 x3 equal to 0 and multiplying the second equation with 2 we get minus 2 x1 plus 4 x2 plus 6 x3 equal to 0.
01:15
So here we get on canceling the common terms 8 x2 plus 8 x3 equal to 0.
01:35
Now solving this a and b we have both values are literally similar.
01:47
So here our final solution is in this equation the solution does not exist.
02:07
So this is the answer.
02:10
Now let us solve the second question using the gauss elimination method.
02:15
So we here we are given with three equations...
