the question is simplY:

solve for 0<x<10

ln(2x+1)<3 cos x

{it is only woth 4 marks, part one, which was worth 2 marks,was what 2 transformations take

ln(x) to ln(2x+1) so i cant see there is to much work here but i cant get it.}

I can see i need to find the points of intersection, but i must be missing something here.

The mark scheme is no help,it just states the answer.
