Hi Ger,
you could e.g. use Solve, like:
eq=2+R Cc+R Bc\[Equal]Ac R
res=Solve[eq,R]
if you do not like the format of the anser, you can change it by e.g.:
res[[1,1]]/.Rule\[Rule]Equal
Another option is to change the equation manually. E.g::
t={eq[[1]],eq[[2]]}
t=t-R Bc
t=Factor[t]
t=t/(Ac-Bc)
if you do not like the format, we can change it:
Equal[t[[2]], t[[1]]]
hope this helps, Daniel
