These things do my nut in...between finding the value of X or Y and then factorising or using the qaudratic formula they just confuse me...anyone have any ideas on how to tackle these or understand them better?as I know these are essential to know!!

Apparently you are doing more complicated problems than linear systems of equations. There may be other general methods, but the only one I am aware of is the substitution method. Otherwise all we can probably do is help you with examples, which we would be glad to do.
