Explicação passo-a-passo:

$A = \large\mathsf{\begin{vmatrix}1&-1\\1&0\end{vmatrix}}$

$\boxed{\boxed{A.A^{-1} = I}}$

$\large\mathsf{\begin{vmatrix}1&-1\\1&0\end{vmatrix}}. \large\mathsf{\begin{vmatrix}a&b\\c&d\end{vmatrix}} = \large\mathsf{\begin{vmatrix}1&0\\0&1\end{vmatrix}}$

$a - c = 1$     $b - d = 0$     $a = 0$     $b = 1$

$A^{-t} = \large\mathsf{\begin{vmatrix}0&1\\-1&1\end{vmatrix}}$
