Use matrix algebra to show that if A is invertible and D satisfies ADequalsI , then Upper D equals Upper A Superscript negative 1. Choose the correct answer below. A. Left-multiply each side of the equation ADequalsI by Upper A Superscript negative 1 to obtain Upper A Superscript negative 1ADequalsUpper A Superscript negative 1I , IDequalsUpper A Superscript negative 1 , and DequalsUpper A Superscript negative 1. B. Add Upper A Superscript negative 1 to both sides of the equation ADequalsI to obtain Upper A Superscript negative 1plusADequalsUpper A Superscript negative 1plusI , IDequalsUpper A Superscript negative 1 , and DequalsUpper A Superscript negative 1.
