Default Quick maths help anyone

i have this question and i can't arrange it to that for the life of me.

The formula:


f = 6x/12z-6y (So it's 6x divided by 12z-6y)

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.

I can get it in the form:

z=x/2f + y/2, is this the correct form?

f = 6x/12z-6y

f(12z-6y) = 6x

12z - 6y = 6x/f

12z = 6x/f + 6y

z = (6x/f)/12 + 6y/12

= answers given above (..in case you gotta show your working and all that)!

yeep, zobers and tigersaw r on the money, my bad!
