I want to be careful when I'm taking negatives through parentheses. If I'm having trouble keeping track of the "minus" signs, I'll put a "1" in front of the parentheses. I have to be sure to take the 7 and the 6 all the way through their respective parentheses. After I'd simplified either side, I moved the smaller of the two variable terms being the "35x" on the left-hand side to ensure that my resulting variable term had no "minus" sign on it. This isn't a "rule", but it certainly does make my life easier. Don't try to do everything in your head. For this equation, I can actually get rid of the 3 by dividing through, because the 6 on the right-hand side is divisible by 3.
