Solving Simultaneous Equations in VB

[ninja1980]

Hi

Another day, another problem.

After all the helpful responses yesterday I thought I ask for some help on the following problem that has been bugging me for quite some time.

I basically need to find the solution for the following simultaneous equations:

Na = (ygo * Ng) + (1-ygo)Nv

a/k*(1/Ng – 1) = Omega(1/Nv – 1)

The only unknowns are Ng and Nv

The only way I can see of doing it is to solve iteratively. I not asking for anyone to solve this problem for me, just to give me some pointers on how to get started.

Thanks

Sorry, the second equation should read

a/k*(1/Ng^2 – 1) = Omega(1/Nv – 1)

You have 2 equations with 2 unknowns, so no iteration required.
Assumption:
Na = (ygo * Ng) + (1-ygo)Nv
should be read
Na = (ygo * Ng) + (1-ygo) * Nv

and thus
Nv = (Na - (ygo * Ng)) / (1 - ygo)

you simply report the above value of Nv in the 2nd equation and then you may get the value of Ng

Hope This Helps, PH.
