A proof may be found at https://leanprover.zulipchat.com/#narrow/channel/458659-Equational/topic/Outstanding.20equations.2C.20v1/near/478054537

The formalized proof may be placed in the ManuallyProved folder. ManuallyProved.lean should be updated afterwards, and the appropriate conjectures from Conjectures.lean removed.

Alternate proof (avoiding translation invariant formalism) at https://leanprover.zulipchat.com/#narrow/channel/458659-Equational/topic/713.2C.201289.2C.201447/near/482084613.2E01

Partial result using translation invariant approach at #860, but none of the one-variable laws
