Best ResponseYou've already chosen the best response.2yah you need to get the x term alone c: requires a lil bit of math there is a positive 15 on the left, subtract 15 from both sides and that will deal with move one of the items to the other side, bringing you closer to solving for x. hope that makes sense c: just post if yer still stuck.
