SOLUTION: The distance between x and 7 is no more than 4. Use absoulute value notation to describe this expression.

When we talk about the distance between 2 numbers, we usually just subtract those numbers to find the distance between them, so:

|x-7|<=4

In words, the absolute value of x minus 7 is less than or equal to 4 (it can be 4, but it can't larger than 4, that is why we use less than or equal to).

We don't know if x or 7 is the bigger number, and when talking about distances, they can most often never be negative, that is where the absolute value comes in to play.

I hope this helps! :)
