Your method is correct, but your denominator is slightly incorrect.

$\displaystyle \frac{ \frac{1}{3} + \frac{1}{y} }{ \frac{y}{3} - \frac{3}{y} }$ $\displaystyle \times \frac{3y}{3y}$

$\displaystyle = \frac{ \frac{1}{3}(3y)+ \frac{1}{y}(3y) }{ \frac{y}{3}(3y) - \frac{3}{y}(3y) }$

$\displaystyle = \frac{ y+ 3 }{ y^2 - 9 }$

$\displaystyle = \frac{y+3}{(y+3)(y-3)} = \frac{1}{y-3}$, $\displaystyle y \neq 3, \, -3, \, 0$

I just need to simplify and reduce to lowest term.

would this be correct?

y+3

----------

(y+3)(y-3)

Thanks. I would like to find out how you make your posts look like they are done in equation editor. Are there any instructions on the site for doing this?

Thanks again for your time

So far, everything I've found on this page works in this forum.

Common examples:

$\displaystyle x^2$

$\displaystyle x_1$

$\displaystyle x_1^3$

$\displaystyle \sqrt{ x^{3/2} }$

$\displaystyle \frac{x-1}{x^2+2x}$

You get used to it after a while. :)
