4. a) Augmented Matrix is:
![Matrices Assignment img4 Matrices Assignment img4](https://www.assignmenthelp.net/webimg/yah/images/matrices-assignment-img4.jpg)
x = -5/11
x = 58/11
= 0
e) The system of equation has no solution.
f) x = No Solution
y=No Solution.

Hence;
X=0
Y=2
Z=-2

8x-3y=h
-32x+12y=8
Divide the second equation by 4
8x-3y=h
-8x+3y=2
Add the 2 equations
0=h+2
h = -2
7. There is no solution when there is a pivot in the 3rd That is when k-12=0 and 2h+5≠0, which therefore means that k=12 and h≠-5/2.
