adam:
The aim is to get x on one side by itself.
Start with things that are 'tacked on' that is numbers that are just added or subtracted after the x term
here you have +3 how do you get rid of +3 well, you take it away.
That is you start by subtracting 3 from BOTH sides.
Then you will need to think about how to get rid of the 2 and do it to BOTH sides.
Then you will have your answer.
