Answer:

The answer to your question is

Step-by-step explanation:

Data

                   4x - 8y = -16    ------------ (I)

                     x - 2y = - 8     ------------ (II)

a) Solve equation II for x

                     x = 2y - 8

   Substitute x in equation I

                    4(2y - 8) - 8y = -16

                    8y - 32 - 8y = -16

                     8y - 8y = 32 - 16

                            0 = 16             The system has no solution because y was

                                                     cancelled.

b) When a system of equations do not have solution means that the lines are parallels and different.
