OF stands for multiplication so you will do 3/5 times b and then you have 7 less than that so you subtract 7 which equals A
3/5b-7=a
Your first option is correct.
EXPLANATION:
your first option is correct because this is a grammar question. When you use "an" you're using it in front of a vowel. The only sentence starting with a vowel is the first one. The others don't sound right when you use "an" in front of it instead of "a".
