Question

The row-echelon form of the augmented matrix of a system of equations is given. Find the solution of the system.

Answer 1

Answer:

option-C

Step-by-step explanation:

We are given row-echelon form

So, we can write equation from matrix as

$x-5z=-3$

$y-4z=-5$

Let's assume

$z=t$

now, we can find x and y

$x-5t=-3$

$x=5t-3$

$y-4t=-5$

$y=4t-5$

so, we get solutions as

$x=5t-3$

$y=4t-5$

$z=t$

where t can be any real numbers
