Q3.1 Solve the linear system Ax=b using Numpy's linear algebra module. What are x1,x2, and x3 ? Eqn (1) 21x2+x3=1 Eqn (2) 31+32+93=0 Eqn (3) 31+32+53=4 Q3.2 Compute and print the inverse of the matrix A (call it Ainv). Then use NumPy to prove the following three identity equations. 1. Ainv * A=I, where I is the identity matrix and "*" denotes matrix multiplication 2. AAinv=I 3. Ainvb=x
