Inverse from Determinant and Adjoint (3x3, with Formula) - Single Value

Question

The determinant is 532 and the adjoint is shown. What is the entry at row 3, column 1 of the inverse? Use $A^{-1} = \frac{1}{\vert A \vert} 	ext{adj}(A)$.

$$\left[ {\begin{array} {ccc} 14 & 81 & 16 \ -56 & -58 & -64 \ \fcolorbox{#1b7f3b}{#e6f7ec}{$-28$} & -10 & 44 \end{array}  } ight]$$
