Unfortunately at one time I loved physics and group theory. I actually thought I was doing mathematics... Then like Saul, I was struck by lightning and saw the light. Computational mathematics!

Hahahaha! That is brilliant!

]]>What did you specialise in??]]>

Basically, I missed out a '2p2' a LOT earlier on, I went through it all over and wrote it again and I was like, where did that 2p2 dissappear?! (I forgot it off one line of algebra)...went through everything and the end three equations were very simple thanks to your guidance. Thank you again. LOVE it when it works!

]]>Maths is SO stressful sometimes and i try SO hard,

Math is hard work for everybody. Go over how you set the problem up there is certainly a mistake there.

]]>Maths is SO stressful sometimes and i try SO hard, i am really good at mental maths but as you can see I am poor at most else, it really drags because i want to do well. thank you again for your help bobby.

]]>From the first equation you get

You substitute for P1 in equation 3. That gives 2 equations with 2 unknowns. Can you solve now?

]]>Did you use equation 1 and substitute for P1 into equation 3?

I tried substituting everything into everything, I keep going round in circles and have two unknowns in every equation. But this can be done apparantly it shouldn't be too difficult. I just cannot see it.

]]>Hi;

Do you know how to use substitution?

I think so, that's what I tried but I always got it wrong!
