Hi,


12( (1)/(4) - (n)/(3) ) < 6n \\ 12( (1)/(4) - (n)/(3)) / 6 < 6 / 6 \\ 2( (1)/(4) - (n)/(3) ) < 1 \\ \\ot2 * (1)/( \\ot4) - 2 * (n)/(3) \\ (1)/(2) - 2 * (n)/(3) \\ (1)/(2) - (2n)/(3) \\ \\ot6 * (1)/( \\ot2) - \\ot6 * (2n)/( \\ot3) < 6 \\ 3 - 2 * 2n < 6 \\ 3 - 4n < 6 \\ - 4n < 6 - 3 \\ - 4n < 3 \\ - 4n / ( - 4) > 3 / ( - 4) \\n > 3 / ( - 4) \: \: \: \: \: \: \: \: \: | \: ( + ) / ( - ) = ( - ) \\ n > - 3 / 4 \\ n > - (3)/(4) = n > - 0.75 \: \: \: \: \: \: \: \: \: \: \: result


Hope this helps.
