3. On the given augmented matrix

Matrices Assignment img3

4. a) Augmented Matrix is:

Matrices Assignment img4

x = -5/11

x = 58/11

    = 0

e) The system of equation has no solution.

f) x = No Solution

y=No Solution.

Matrices Assignment img5

Hence;

X=0

Y=2

Z=-2

Matrices Assignment img6

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.
