Which looking at your post is what you have done. Pretty straight forward rearraging to make M^-1 the subject yes?

I've got this p*ss easy simultaneous equation to solve, and it says solve it by the matrix inverse method though, is that just Cramers rule?

TBH, I'm not sure, it's been awhile since I did anything specific regarding matrices.  I'd imagine it just wants you to premultiply your matrix equation,

Mx=z,

by the inverse of M such that

x=(M^-1)z.

Can't really remember Cramer's rule TBH but if it looks right, give it a try.

(4/3)(x^0.5 + 1)^1.5 - 4(x^0.5 + 1)^0.5 + integrating constant

Not meaning to be condascending but I don't see what your problem is.  Where are you having the difficulty?  Get everything within the integral in terms of u and integrate. 

Sweet sweet irony.

You should do as these maths threads are a f***ing embarrasement. You know Henry Winter has been on here recently?

You think this is a good reflection of the geordie faithful? Maths threads? Its enough putting up with everyone banging on about american television as some sort of 'experience' without havng to deal with algebraic w***-fests.

:lol:
Whether it's God or the bomb
It's just the same
It's only fear under another name
And the corporate snakes coming in to feed
On that pathetic fact known as human greed
Skin and bone being raked over those hot coals
This dump never seems to give time for human soul
