Trying to solve an equation with variables

[dscot]

Hi,

So I have this simple equation that I'm trying to solve in mathematica , the problem is that although I have all the different values and equation I can't seem to get the solve command to solve it - http://screencast.com/t/a8REzNM0cxSS

Any thoughts on what I'm doing wrong?

Dave,

I guess you are using the wrong syntax.
Have you looked up the help information for Solve?
