Question

Matrix A = (3 x 3)

Row 1 is: 5   -2   2

Row 2 is: 0   3  -3

row 3 is: 2   -4   7

part ii) Using Cramer’s rule (please compute all the required determinants) to find x3 component of the solution to:

Ax = (3 x 1)

Row 1 is:   0

Row 2 is:   1

Row 3 is:    0

What is this value in determines of A−1 ? 

May you please througougly go through your steps using Cramer's rule, as it is extrememly confusing to me

 

part iii) Consider now (n×n) matrices A, B. Let P be an invertible (n×n) matrix such that:

P-1 AP= B.

Derive:   det(A) = det(B)
