In this question, we are told that the augmented matrix of the given system equations could be reduced to the matrix given below.
00:09
And using that, we are asked to write down the parametric solution set.
00:16
The solution set in parameter vector form.
00:19
And to do that, let's just write down y by 1, the equations corresponding to the lines in the given matrix.
00:29
So the first line corresponds to the equation.
00:31
Equation x minus 4 z minus 5 u equals to 1.
00:41
The second equation, so first of all, note that each column corresponds to one variable.
00:47
The first column corresponds to x, the second column is y, the third is z, the fourth is w, and the fifth is u.
00:55
And the last column is the right -hand side.
00:59
So the second line corresponds to the equation y minus 2 z...
