Hi, could someone give me hand solving this inequality, not sure what to do.

$\displaystyle \frac{x}{2} > 2 + \frac{9}{x}$

Multiply by 2

$\displaystyle x > 4 + \frac{18}{x}$

Rearrange a little

$\displaystyle \frac{18}{x} + 4 - x < 0$

Not sure where to go from here? Would the best method to multiply by $\displaystyle x^2$ or is there a better way?

Thanks in advance
