Proof step 4 from proof eq-stream-to-list-2-1 (previous step)

⌜x + y⌝ = ⌜z⌝ ⊦ x + y = z

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: stream-basic inst: name: inj-02 seq: ⊦ ⌜x⌝ = ⌜x0⌝ ↔ x = x0 subst: [x0, x] → [z, x + y] flags: rewrite

Additional information

Used terms: z, x + y
