Question 1132143

{{{((x + 1)/(2x + 4)) >= 3}}}, {{{x <> 2}}} 


{{{((x + 1)/(2x + 4)) -3>= 0}}}


{{{((x + 1)/(2x + 4)) -3(2x + 4)/(2x + 4)>= 0}}}


{{{((x + 1) -3(2x + 4))/(2x + 4)>= 0}}}


{{{(x + 1 -6x -12)/2(x + 2)>= 0}}}


{{{(-5x -11)/2(x + 2)>= 0}}}


{{{x<=-11/5}}}


solutions:


{{{(-5x -11)>= 0}}}=>{{{x<=-11/5}}}


{{{2(x + 2)>= 0}}}=>{{{(x + 2)>= 0}}}=>{{{x >= -2}}}


{{{-11/5<=x<-2}}}

interval:

[{{{-11/5}}}, {{{-2}}})
