Put $b = 0$ and then examine the resulting equations

Ik this step but I just think

#

If i put b=0 into (E)

#

Then I use Gaussian Elimination

#

I can't obtain the row echelon form

#

keen surge Then I use Gaussian Elimination

Why?

#

Is that like a course requirement?

No

Substituting 0 for b in $E$ we get the system

$$2ax - 2z = 5$$
$$3x - az = 0$$
$$x + az = 0$$
