    No solution

    Step-by-step explanation:

    from the second equation x = - 8 + 2y

    By substituting in the first equation 4 (-8 + 2y) - 8y = - 16

    -32 + 8y - 8y = - 16

    -32 = - 16

    the left hand side not equal the write and side

    So there is no solution for the system of equations

    means the two lines are parallel
