Answer 1

Step-by-step explanation

Since we have the determinant:

`A=\begin{bmatrix}{15} & {-5} \\ {-3} & {1}\end{bmatrix}`

Computing the inverse:

`A^(-1)=(1)/(15*1-(-5*-3))*\begin{bmatrix}{1} & {5} \\ {3} & {15}\end{bmatrix}`

Multiplying terms:

`A^(-1)=(1)/(15-15)*\begin{bmatrix}{1} & {5} \\ {3} & {15}\end{bmatrix}=(1)/(0)\begin{bmatrix}{1} & {5} \\ {3} & {15}\end{bmatrix}`

In conclusion, the Inverse Matrix is not possible.
