Thread: Just a Pre-calc problem (testing forum)

1. Just a Pre-calc problem (testing forum)

4/x+5 > 1/2x+3

$\frac{4}{x}+5 > \frac{1}{2x}+3$

or

$\frac{4}{x}+5 > \frac{1}{2}x+3$

3. 4 > 1
x+5 2x+3

also, how did you post a fraction like that?
thanks!

4. This one?

$\frac{4}{x+5} > \frac{1}{2x+3}$

Click on the text, it will tell you.

5. Ok, I see. Yes, that's the one!

6. $\frac{4}{x+5} > \frac{1}{2x+3}$

Well first off you cross multiply giving...

$4(2x+3) >x+5$

Then expanding the LHS you get...

$8x+12 >x+5$

Can you finish it from here?
