Re: I need to know how it this equation was rearranged



q=Qmax(KdCw / 1+KdCw)
(1+KdCw)q=QmaxKdCw
q+KdCwqQmaxKdCw=0
Kd(CwqQmaxCw)=q
Kd=q/(QmaxCwCwq)
Kd=q/((Qmaxq)Cw)

Kd= q / (Qmaxq) Cw is the rearranged
but I need to know step by step which was the process to obtain
de second equation rearranged or if someone have the rules to separate
variables I'll be grateful.

The rules are high school algerbra I would imagine.
I also imagine you have a mistake in your notation
q=Qmax(KdCw / 1+KdCw)
should be
q=Qmax(KdCw / (1+KdCw))
and
Kd= q / (Qmaxq) Cw
should be
Kd= q / ((Qmaxq) Cw)
Because I'm assuming you are using "/" to represent what in your
textbook is drawn with a horizontal line.
in which case doing it by hand, the steps would be
q=Qmax(KdCw / (1+KdCw)) to
q=(QmaxKdCw)/(1+KdCw) to
q + qKdCw = QmaxKdCw to
qKdCw  QmaxKdCw = q to
Kd(qCwQmaxCw) = q to
Kd = q/(qCWQmaxCw) to
Kd = q/((qQmax)Cw) to
Kd = q/((Qmaxq)Cw)

Try it one step at a time. I imagine that there must be an error in your
original.
q=Qmax(KdCw / 1+KdCw) original
must really be:
q=Qmax(KdCw / (1+KdCw)) original
The parenthesis are not optional.
I have not bothered to work it out, but consider (for instance) that 1 =
Cw/Cw {assuming that Cw cannot become 0} and I think that might get you
started.
