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.
