The formula:

can be rearranged in the form:


z = A x/f + By (So it's A then x dived by f plus By)

where A and B are fractions.

Tried Wolfram Alpha?

good job you didnt throw in something like this

what does the algebra actually do? is it useful for anything?

For absolutely loads of things!!

Doctors use it for calculating dose ratios for given weights, and various other more complex things.

Pilots for navigation, engineers in designing and constructing things...physicists/space..

Analysing the market and coming up with figures.

Algebra is sooo important for many people and professions...though it may seem pointless and irrelevant at school!

I must admit to being a bit worried - for my next OU course I'm doing Technology of music which has.....algebra looking type maths in it! I'm gonna fail............

i guessing you do maths a lot?

aww man I wish. Shudda done maths or physics at uni or something. Learning about diseases from a textbook is soo much more mind numbing. Committing things to memory (at least at my stage now) is so much lamer than working things out for yourself.

Du get to do a lot of algebra studying computer security then?

just tick c

We have one module called analytical modelling that is all maths.
