Use matrix algebra to show that if A is invertible and D satisfies AD = I, then D = A™ 1. Choose the correct answer below. 1 -1 A. Right-multiply each side of the equation AD = I by A1 to obtain ADA¯¹ = IA¯¹, DI = A¯¹, and D=A¯ O B. Left-multiply each side of the equation AD = I by A1 to obtain A¹ AD = A¯¹I, ID = A¯¹, and D=A¯¹. OC. Add A 1 to both sides of the equation AD = I to obtain AD + A1 = I+A¯¹, DI = A¯¹, and D=A¯1. OD. Add A 1 to both sides of the equation AD = I to obtain A1+AD=A1 + I, ID = A¯1, and D=A¯1.

Question
Use matrix algebra to show that if A is invertible and D satisfies AD = I, then D=A¯¹. Choose the correct answer below. A. Right-multiply each side of the equation AD = I by A1 to obtain ADA 1 = IA1, DI=A1, and D=A¯1. 1 Left-multiply each side of the equation AD = I by A¹ to obtain A¯¹AD = A¯¹I, ID = A¯¹, and D = A¯¹. C. Add A¯¹ to both sides of the equation AD = I to obtain AD + A¯¹ = I + A¯¹, DI = A¯1, and D = A¯¹. D. Add A¹ to both sides of the equation AD = I to obtain A¯ 1 + AD = A¯¹ + I, ID = A¯1, and D = A¯¹. B.
