Well, good luck if anyone is.
That plank question was a complete biatch!

1/x = 3/2x + 1/(x+1)
=> 2/2x = 3/2x + 1/(x+1)
=> -1/2x = 1/(x+1)
=> -1(x+1) = 1(2x)
=> -x-1 = 2x
=> 3x = -1
=> x = -1/3
I've got M1 with Edexcel tomorrow!

I did P1,P2,P4 and P5 for A-level. We were only allowed to use graphics calculaters for P1 and P4 :(
I failed all of them except for P1. Got a C in that one which i was quite shocked at. Only passed Maths becasue of my high grades in the statistics modules.
1/x = 3/2x + 1/(x+1)
So in words
1 over x = 3 over 2x + 1 over x+1
Working please!
I have D1, S1 and a Physics exam next week. Should be entertaining. I might actually revise for them.
