using Cramer's rule:
let 5x+ 6y +7z= 9
[ 5 6 7] [ x y z ] = [9]
here consider X→ [5 6 7 ]
to find values of x ,y and z .
we need to find values of determinant to find values of using Cramer's rule but we can't find determinant of X , this means we can't solve upper question using Cramer's Rule.
Hope you are satisfied with explanation.
