which is your problem?

\(\displaystyle \frac{4}{x}+5 > \frac{1}{2x}+3 \)

or

\(\displaystyle \frac{4}{x}+5 > \frac{1}{2}x+3 \)

\(\displaystyle \frac{4}{x+5} > \frac{1}{2x+3}\)

Well first off you cross multiply giving...

\(\displaystyle 4(2x+3) >x+5\)

Then expanding the LHS you get...

\(\displaystyle 8x+12 >x+5\)

Can you finish it from here?
