  1. Let the two consecutive numbers be x and x+1
    translating "The sum of 2 consecutive integers is equal to their difference" ---> x + x+1 = x+1 - x

    I trust you to solve for x

  2. x + x + 1 = x + 1 - x

    -x + x + x + 1 = x + 1 -x + -x

    = x + 1 = x + 1 = 2x

    x = 1 = 1 = x + 1 -1 - 2x

    x = x = 2x

    3 = 3 - 2 * 3 = [-3]

  3. x + x + 1 = x + 1 = x

    x + x + x + 1 = x + 1 - x + x

    3x + 1 = x + 1

    -x + 3x + 1 = -x + x + 1

    2x + 1
