Help with math

OK assume 200nl 6max with $200 effective stacks.

Folded to hero on CO who raises to 7.
Villain is D and 3bets to 24.
Hero shoves.

Now, I predict that 80.2% of the time villain will fold, where we win 24+3(blinds)+7= $34

19.8% of the time villain will call. I would like to know what the breakeven % for villains range will be.

So. X% of the time we will win $200 from villain. (100-X)% of the time we will lose $200 to villain.

So, (80.2)(34) + (200)(X) - (200)(100-X) = 0

This comes out at 48%ish and that has to be wrong. I'm assuming the parts where we have inserted 200 is wrong. Can anyone correct it please?
