  1. first:

    0x + 2y = 140

    which means

    2y=140

    so u divide 140 by 2

    and getttttt>>>>

    y=70


  2. -7x + y = 71, 7x + y = 69

    (-7x + y = 71) + (7x + y = 69) = (2y = 140)

    2y = 140

    y = 70

    -7x + y = 71

    -7x + 70 = 71

    -7x = 1

    x = -1/7

    ANSWER: x = -1/7, y = 70
