Problem: Solving Vmax equation with HP Prime

[Aries]

I recently got a HP Prime and am trying to solve a chemistry equation with little success. The formula appears below and calculating the result using traditional methods required two passes.


V = (Vmax * S) / (Km +S)

V and S are given and we need to calculate Vmax and Km

Manually we solve first for Vmax and then substitute that answer into the equation again to resolve for Km

I have tried countless ways of entering this in the Prime but I cannot get any valid results.
Can someone provide guidance on how I would go about solving this in the HP Prime

Thanks

You have two unknowns but only a single equation.
You can't solve for two unknowns with only one equation (unless there are unusual side conditions).
Being the equation linear, you can solve for Vmax in terms of Km or Km in terms of Vmax.
