<u><em>Answer:</em></u>
a. A number divided by fourteen minus 3
<u><em>Explanation:</em></u>
Before we begin, remember that:

is read as "a" divided "b"
Now, for our given:

<u>For the first term</u>, we have a given number "x" divided by 14
<u>For the second term</u>, we have three
<u>The operation</u> between the two terms is minus
Combining the above, we can deduce that:
