If $A$ and $B$ are two matrices of order $3*3$ and $det(A)= 4$ and $det(B)= 5$ , then the value of $2det(A)-2det(B^{-1})$ is? If $A$ and $B$ are two matrices of order $3*3$ and $det(A)= 4$  and $det(B)= 5$, what is the value of $2det(A) - 2det(B^{-1})$?

Hint
If $M$ is an invertible matrix then
$$\det\left(M^{-1}\right)=\frac1{\det M}$$
