Dear
case 1 (x+4)/2 >1
x> -2
log(x+4)/2{log2(2x-1)/(3+x)}<0
so 0 < log2(2x-1)/(3+x) <1
1 < (2x-1)/(3+x) < 2
1 < (2x-1)/(3+x) and (2x-1)/(3+x) <2
x>4 and for all x
so solution is x>4
case 2 0<(x+4)/2 <1
-4 <x<-2
log(x+4)/2{log2(2x-1)/(3+x)}<0
so log2(2x-1)/(3+x) >1
(2x-1)/(3+x) > 2
now again let x+3 > 0
2x-1 > 6+2x
no solution
x+3 <0
x<-3
so 2x-1 < 6+2x
all x
so final solution is -4<x<-3
so solution for x is -4<x<-3 and x>4
