Another Two-Voice Question

[Will Oram]

Thanks for the answer supplied long ago for how to connect similar 
noteheads of different voices. Once I got lilypond back up on my 
computer it worked nicely.

Then, tonight, I came upon this to balance:
  __________
 |    ------|
 |          |
* .   *    *
     |    |
7    |    |
      ----
     3

In other words, a dotted eighth beamed to a sixteenth. The lower voice 
is a triplet of eighths, the first of which is a rest. The last 
notehead is the same for both voices.

If everything were eighths like I was used to, it would be 8*4/3 then 
8*2/3. I tried a lot of math to get an equivalent for the above. I got 
8*5/3 and 16*1/3, which lilypond didn't like.

What's the best way to work this?
