    2x + 14y = - 8

    2x + 14 (0) = - 8

    2x + 0 = 8

    2x = 8

    2 2

    x = 4

    (x, y) = (4, 0)

    7x + 14y = 14

    7x + 14 (0) = 14

    7x + 0 = 14

    7x = 14

    7 7

    x = 2

    (x, y) = (2, 0)

    10x + 2y = 20

    10x + 2 (0) = 20

    10x + 0 = 20

    10x = 20

    10 10

    x = 2

    (x, y) = (2, 0)

    Y=0

    2x+14y=-8 ... x=-4

    7x+14y=14 ... x=2

    10x+2y=20 ... x=2
