$5 n - 3$ $5n-3$

Explanation:

Less than a number should clue you in to subtraction after a number.
So $x$ $x$ less than a number means $n - x$ $n-x$ . In this case 3 less than a number is $n - 3$ $n-3$ .

Times means multiplication. $c$ $c$ times a number is $c$ $c$ x $n$ $n$ . In this case $5$ $5$ times a number is $5$ $5$ x $n$ $n$ .

Altogether, 3 less than 5 times a number is $5 n - 3$ $5n-3$ .
I used $n$ $n$ for 'a number' because number started with $n$ $n$ . You can use any letter.
