Question 40714
This problem is asking you to translate from English words to math symbols.  You may want to review and memorize the list of translations in your book because this is a very important concept in algebra that you will see again and again.

In your problem: 

2 times a number, increased by 28, is less than or equal to 6 times that number.

The unknown number is represented by "x".  But in other problems, it could be any other letter.  Just remember that since we don't know the value of this mystery number, an "x" is used.

The word "times" means to multiply.  "Increased by" means to addition.  "Less than" is the math symbol <.  "Equal to" is the math symbol =.  "Six times that number" means that we are to multiply the unknown number by 6.

So, putting all of the math symbols together:

2x + 28 <= 6x
