100.04 = 9/5 C +32
68.04 = 9/5 C (subtract 32)
37.8 = C (multiply by 5/9)

That's from subtracting the 32 from both sides. 100.04-32=68.04

I get 36.04 instead of 37.08

Oh I'm sorry, the numbers are correct, but I misspoke about where it was from. Subtracting 32 is the prior step, and that gets you 68.04. The next step you want to get rid of the 9/5 still multiplied to your unknown C, and you do this by multiplying
by the reciprocal of 9/5, which is 5/9. You can think of this as two steps. Multiply by 5, then divide by 9, or one step of multiplying by 5/9. That gives you the final 37.08. Sorry for the confusion.
