Challenge: Solving the Task Using SLE

We have already considered how to solve the SLE using inversed matrix. But we can also use np.linalg.solve(A, y) method that calculates the solution of the SLE:
A * x = y.
Your task is to solve the system using both these methods and compare the results:

1. Use np.linalg.solve() method.
2. Use np.inv() method to calculate inversed matrix and provide solution using: x = A_inv @ y.
