Find the exact solutions x and y = Ax to the least squares problem min∥b− Ax∥2 (not by Python). What is the relative error for the numerical solution obtained in part (a)? (The relative error is ∥x−xˆ∥1/∥x∥1, you can also use other norms.)

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
