Proof step 8 from proof modeqp (previous step)

i1 -1 * j + j0 = i0 * j + j1, 0 ≤ j0, j0 < j, 0 ≤ j1, j1 < j, 0 < j, ∀ j, j0, i0, j1. i1 * j + j0 = i0 * j + j1 ∧ 0 ≤ j0 ∧ j0 < j ∧ 0 ≤ j1 ∧ j1 < j ∧ 0 < j → i1 = i0 ∧ j0 = j1 ⊦ i0 + 1 = i1 ∧ j0 = j1

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals
