Hi,

For some reason i'm struggling to rearrange a lot of equations where i'm attempting to make a variable that appears twice in the equation the subject. At the moment i am attempting to rearrange this equation to make D the subject. May someone please show me how to do this in steps please?

$\displaystyle A=B*D*(1/(C+D))$

And if possible, i would like some tips on how to make variables that appear twice the subject please?

Any help is much appreciated

Rob
