1. ## Simple Algebra?

I am working on a Centroid Integration problem, and I am having problems rearranging a simple equation in terms of x. Can you have a look at this and tell me if I am going mad?

y = h/b (b - x)

should be x = b/h (h - y)

Is that right?

thanks to those who help.

2. looks good...

I find it easier to "see" if these are posted this way: y = h(b - x) / b

Or even better:

$y = \frac{h(b-x)}{b}$

You can always just click on the LaTex equations in anyone's posts to see the exact markup used to create it.

5. Its part of a larger problem involving centroid of triangle by integration, Its probably best to leave it as $x=\frac {b}{h}(h-y)$

6. You're missing the point Cess.
