In problems 5 - 6, find the inverse of each matrix by the row-reduction method. Problems 7 -10: Express the system as \(AX = B\); then solve using matrix inverses found in problems 3 - 6. Problems 9 -10: Express the system as \(AX = B\); then solve using matrix inverses found in problems 3 - 6. Suppose we are solving a system \(AX = B\) by the matrix inverse method, but discover \(A\) has no inverse.
