Data Sufficiency

say, you know that n divided by 3 gives you remainder 2
and you also know that n divided by 5 gives you remainder 2
THEN, what is the remainder when n is divided by 15?
Please provide detailed explanation.

Here is how far i got

n = 3A + 2
n = 5B + 2

But how do you combine the two statements to figure out what the remainder when n is divided by 15 is??

Thanks!
