Find the specified element in the inverse of the given matrix

What is the given matrix?

you didn't show a matrix.

the components of the matrix are the elements.

and the elements of the inverse matrix are the elements of the inverse matrix

1)

so if matrix A is 1 4 1

2 5 2

3 6 3

2)

14114

25225

36336

3)

15 24 12

15 12 24

4)

[A] = (15+24+12=51) - (15+12+24=51)

[A]=0

5)

52 23 25

63 23 36

41 11 14

63 33 36

41 12 14

52 12 25

6)

15-12 6-6 12-15

12-6 3-3 6-12

8-5 2-2 5-8

7)

3 0 - 3

6 0 - 6

3 0 - 3

8)

(+) 3 (-) 0 (+) - 3

(-) 6 (+) 0 (-) - 6

(+) 3 (-) 0 (+) - 3

=

3 0 - 3

-6 0 6

3 0 - 3

9)

3 - 6 3

N = 0 0 0

-3 6 - 3

10) the inverse of [A] = 1/|A|*[N]

which is in this case ⁻A = 0

because |A|=0
