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.
