Answer 1

Answer:

Step-by-step explanation:

1. Find A- using determinent method.

i Form cofactor matrix

ii do it's transpose for adjoint matrix

iii at last divide adjoint matrix by |A| you will get A-

2. after finding A- solve your question using equation

              X=A-B

where X=[x]

               [y]

               [z]

and A- is inverse of matrix A

and B is [27]

              [16]

              [19]

You will get your answer

• Find |A| using discriminant method.
• form co factor matrix
• Do it transpose for adjacent matrix
• at last,divide adjoint matrix by |A| ,you 'll get A
• After finding A solve your question using equation
• X=A-B
• where X=x,y,z
• and A is inverse of matrix A ¡.e |A|
• so B is {27},{16},{19}
