input: Write a python function to solve a system of linear equations using numpy.
  assert np.allclose(solve_linear_equations([[2, 3], [5, 6]], [1, -2]), [-8, 6])
  assert np.allclose(solve_linear_equations([[1, 2], [3, 4]], [3, 7]), [-1, 2])
  assert np.allclose(solve_linear_equations([[4, 5], [7, 8]], [2, 3]), [-1, 2])
output: import numpy as np
  
  def solve_linear_equations(A, b):
      A = np.array(A)
      b = np.array(b)
      solution = np.linalg.solve(A, b)
      return solution.tolist()
