Answer:

b (x, x - 3, 0)
d Infinite Solutions

Step-by-step explanation:

1. A graphing calculator or any of several solvers available on the internet can tell you the reduced row-echelon form of the augmented matrix ...

$\left[\begin{array}{ccc|c}2&-2&-1&6\\-1&1&3&-3\\3&-3&2&9\end{array}\right]$

is the matrix ...

$\left[\begin{array}{ccc|c}1&-1&0&3\\0&0&1&0\\0&0&0&0\end{array}\right]$

The first row can be interpreted as the equation ...

x -y = 3

x -3 = y . . . . . add y-3

The second row can be interpreted as the equation ...

z = 0

Then the solution set is ...

(x, y, z) = (x, x -3, 0) . . . . matches selection B

2. The second equation is 2 times the first equation, so the system of equations is dependent. There are infinite solutions.
