# Homework Help: Rearranging Equations

Alright I'm going absolutely nuts here. It's a simple matter of rearranging an equation and for the life of me I can't do it. I've been working at it for like an hour now to no avail. Here's the equation.

P=[RT/(v-b)]-[a/v(v+b)T^0.5]

I'm trying to solve for v. I've manipulated this equation every way I can think of and still can't get it. I'm sure it's something simple but I'm stuck. Please help.
Thanks

Staff Emeritus
Can you put either put redundant parenthesis around everything or put the equation in LaTeX format (tutorial is in the general physics stickies)?

As enigma suggests, there is quite a bit of ambiguity in how you wrote your equation. Here are a few of the possible ways we could interpret what you wrote.

The first part of your equation could be R[T/(v-b)] or (RT)/(v-b)
The second part could be
[(a/v)(v+b)(T^.5)] or
{[a/(v(v+b))](T^0.5)} or
{(a/[v(v+b)(T^0.5)]}

Can you clarify?

Your question appears the same as the one you posted on engineering homework: query.
Did you mean to post it as a math question or engineering?
