Answer 1

The sentence

"Distance of 5 units from the number 7"

The part "From the number 7" indicates that you have to start counting from 7 on. Then the left bound of the interval is number 7.

To determine the right bound of the interval you have to count 5 units starting from 7, so add 5 to 7

`7+5=12`

The right bound of the interval is 12.

So, the values of x within the distance described by the sentence are: (7,12)
