1. http://qualifications.pearson.com/co...-June-2014.pdf

for question 5 (and these types of questions in general), could you be marked down for squaring both sides and solving a quadratic inequality as opposed to using a graphical method?
2. Since it doesn't specify what method to do, I would say as long as you get all the correct answers you will be fine. It may say in the mark scheme, as there are sometimes alternative methods in there.

I personally wouldn't solve it graphically. I would solve both 4x - 3 = 2 - 2x and -(4x - 3) = 2 - 2x but everyone has different methods and, as long as the question doesn't specify (and you get the right answer), just do what works for you.
