Let\[\left \lfloor x \right \rfloor\]be the greatest integer not exceeding\[x\]
and let\[\left \{ x \right \}\]be the fractional part of the real number\[x\].
Find all positive real number\[x\]
such that\[\left \{ \left (2x+3 \right )/\left (x+2 \right ) \right \} + \left \lfloor \left ( 2x+1 \right )/\left ( x+1 \right ) \right \rfloor = 14/9\]
I'm just getting started with latex (I know um aweful! at it) and BDMO. expect more contribution from me.

Re: From the Mayhem. (Again)
i am not sure whether it is right or not, but my solution is such
here is just a little experience about $LaTeX$ which may help you.
just have an one hour experiment with the equation editor
and, to the authority - i think this topic should be moved to any other problem forum,as it is not any part of BDMC

Seems like you missed a $\{ \}$ there... must be a typing mistake...nafistiham wrote:i am not sure whether it is right or not, but my solution is such

sorry. editing that. but is the solution all ok?
