So basically, if you want to isolate a term on a side, you kind of do I backward pemdas, where you add or subtract the constant on the side with the variable, then multiply or divide by the coeffiecient of your x, then do the same thing within parenthases. If you have variables on both sides, all you do to get it on one side is add or subtract the variable term on either side, simplify, then solve as you would a normal equation.
