Proof sketch can be found at https://leanprover.zulipchat.com/#narrow/channel/458659-Equational/topic/Outstanding.20equations.2C.20v1/near/477846456

Proof can go in the ManuallyProved folder. ManuallyProved.lean should be updated afterwards, and the appropriate conjectures from Conjectures.lean removed.
