    Step-by-step explanation:

    first solution

    we take

    y = 2

    2x – y = 20

    2x – 2 = 20 (y = 2)

    2x = 20 + 2

    2x = 22

    x = 22/2

    x = 11

    second solution

    we take

    y = -2

    2x -y =20 (y = -2)

    2x – (-2) = 20

    2x +2 = 20

    2x = 20-2

    2x = 18

    x = 18/2

    x = 9
