Question:Matrix operations - extract element equations?

Hello

 

I want to create three matrices, multiply two of them, equate the result to the third, and extract the individual matrix element equations:

A:=Matrix(2,2,[1,2,3,4]);

B:=Matrix(2,2,[2,3,4,5]);
                      
C:=Matrix(2,2,[a,b,c,d]);

M:=evalm(A&*B);

N:=M-C;

solve(N[2,2]=0,d)

By doing something like this, I want the output d=29, but I get nothing. My multiplication of the matrices is causing the error, as seen from the output of N:=M-C. What to do?
