If you are trying to find the value of n you need to first make an equation. When it says "half a number n" that means that you have one half times n. Then you add 7 because it says "and 7." Finally when it says is at most that means the total. So for this equation, it would be 20. So the equation would be 12n+7=20. Then you subtract 7 from both sides.
12n=13
Then you have to multiply by the reciprocal which is 2.
212n=2(13)
Then your 12 and 2 will cancel so you are left with:
n=26
