    x=4

    y=1

    Step-by-step explanation:

    7x + 14y = - 14

    -2 / 8x + 7y = - 25 (multiple it with - 2 then add it with other equation)

    7x + 14y = - 14

    -16x - 14y = 50

    -9x = 36

    x = - 4

    put the value in its place for the first equation

    7 • - 4 + 14y = - 14

    14y = - 14 + 28

    y = 1
