Proof step 7 from proof get-eqex-03 (previous step)

eqex(st, st0, r0), eqex(st0, st, r0) ⊦ ∀ j0. 0 ≤ j0 ∧ j0 < j → st0[r -- (i + j0) '] = st[r -- (i + j0) '], r = r0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
j0 < j, eqex(st, st0, r0), eqex(st0, st, r0), 0 ≤ j0, 0 < j ⊦ st0[r -- (i + j0) '] = st[r -- (i + j0) '], r = r0

Rule argument
