Proof step 11 from proof cong-mult-rew (previous step)

j | i0 - i2 ⊦ j | i * i0 - i1 ↔ j | i * i2 - i1

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-gcd inst: name: divides seq: ⊦ i | j ↔ (∃ i0. i * i0 = j) subst: [j, i] → [i0 - i2, j] flags: rewrite

Additional information

Used terms: i0 - i2, j
