This level is similar to the earlier level where numbered circles were connected with the corressponding number of lines. So consider that A=1, B=2 and so on, you need to change the Xs with the correct number of lines that should interconnect the circles. Therefore, the solution will go like this:
Between D and E = 4
Between E and B = 1
Between B and E = 1
Between A and E = 1
Between E and C = 3
