Proof step 60 from proof lemma3-2 (conclusion)

⊦ eqds(sys, sources(co + cl, d), sys0) ∧ eqS(sys, sys0) → eqds(step(sys, co), sources(cl, d), step(sys0, co))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ eqds(sys, ds, sys0) ↔ (∀ d. d ∈ ds → eqd(sys, d, sys0))
