WebJul 9, 2024 · For instance, you can solve the system that follows by using inverse matrices: Write the system as a matrix equation. Create the inverse of the coefficient matrix out of the matrix equation. In this case, a = 4, b = 3, c = –10, and d = –2. Hence ad – bc = 22. Hence, the inverse matrix is. Multiply the inverse of the coefficient matrix in ... WebQuestion: Show that B is the inverse of A. A = 1 2 5 8 , B =. Find the inverse of the matrix (if it exists).
