Melanie Walsh · Answer 1

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.
