so it is not as simple as solving for F? (i hope i don't come across as rude here but) i'm not looking for advice on how to 5bet unexploitably/play optimally vs 4bets or anything broad like that. i'm simply after pointers in where i'm going wrong in the mathematical procedures involved in the above equation. is your above post extrapolating from my original question? or is it genuinely an extremely complex process, to the point of requiring a computer, to figure out F in

F = (-201.5y + 111.5) / (75 - 201.5y)

if we are given a y value?

again, i'm relatively clueless when it comes to this stuff, so forgive me if i'm wrong.
