Question:

Problems 23 through 26 introduce the idea—developed more fully in the next section—of a multiplicative inverse of a square matrix.

Let

and

Find B so that AB = I = BA as follows: First equate entries on the two sides of the equation AB = I. Then solve the resulting four equations for a, b, c, and d. Finally verify that BA = I as well.
