Solve each of the following matrix equations for X:
a) AX=C
b) AX+D=C
Where A= ⎡2 1 2⎤, C=⎡2⎤and D= ⎡-1⎤
⎢0 1 6⎥ ⎢0⎥ ⎢0 ⎥
⎣2 1 0⎦ ⎣2⎦ ⎣3 ⎦
Thanks in advance.

a)
b)
To get the inverse matrix you either have to follow the procedure that will be outlined in your textbook or class notes, or use a CAS. Since A is 3x3 matrix the former approach will require some small amount of time and effort on your part.
