    We are given the two equations:

    (1) - x=29-14y

    (2) - 9x=-19+14y

    Multiply (1) by 9:

    -9x = 261 - 126y

    Subtract the two equations:

    -9x = 261 - 126y

    -

    -9x=-19 + 14y

    0 = 280 - 140y

    140y = 280

    y = 2

    From (1):

    -x = 29 - 14 (2)

    x = - 1

    Answers:

    x = - 1

    y = 2
