input: Write a python function to solve a system of linear equations using numpy's linalg.solve method.
  assert solve_linear_system([[2, 3], [5, -1]], [8, -10])==[2.0, 1.0]
  assert solve_linear_system([[1, 2], [3, 4]], [5, 6])==[-4.0, 4.5]
  assert solve_linear_system([[4, 2], [3, 1]], [10, 9])==[2.0, 1.0]
output: import numpy as np
  
  def solve_linear_system(coefficients, constants):
      coefficients = np.array(coefficients)
      constants = np.array(constants)
      solution = np.linalg.solve(coefficients, constants)
      return solution.tolist()
