    Let x be the number.

    Then twice the number is 2x.

    The difference between twice the number and seventeen is 2x-17.

    At last, a number added to the difference between twice the number and seventeen will take a look:

    (2x-17)+x.

    You can simplify it:

    (2x-17)+x=2x-17+x=3x-17.

    Answer: (2x-17)+x=3x-17.
