    Answer:

    These system of equations have no solution.

    Step-by-step explanation:

    We need to solve the system of equations

    2x + 4y = 16\\4x + 8y = -16

    by eliminating variable y

    Let:

    2x + 4y = 16--eq(1)\\4x + 8y = -16--eq(2)

    Multiply eq(1) by 2 and subtract both equations

    4x + 8y = 32\\4x + 8y = -16\\- \ - \ \ \ \ \ \ \ +\\---------\\0x+0y=48\\0\neq 48

    As 0≠48

    So, these system of equations have no solution.
