Proof step 1 from proof rm-vl-append-same (conclusion)

⊦ q + eq-entry(n, lref) ' - lref = q - lref

Heuristic structural induction applied rule structural induction

And obtained the following new goals

Proof step 2:
⊦ [] + eq-entry(n, lref) ' - lref = [] - lref
Proof step 9:
∀ n, lref. q0 + eq-entry(n, lref) ' - lref = q0 - lref ⊦ (eqent + q0) + eq-entry(n, lref) ' - lref = eqent + q0 - lref

Rule argument

term: q
