(7) RewriteLemmaProof (LOWER BOUND(ID) transformation)

Proved the following rewrite lemma:
activate(gen_n__0:n__plus:n__s:n__x3_7(n5_7)) → gen_n__0:n__plus:n__s:n__x3_7(n5_7), rt ∈ Ω(1 + n5₇)

Induction Base:
activate(gen_n__0:n__plus:n__s:n__x3_7(0)) →_R^Ω(1)
gen_n__0:n__plus:n__s:n__x3_7(0)

Induction Step:
activate(gen_n__0:n__plus:n__s:n__x3_7(+(n5_7, 1))) →_R^Ω(1)
plus(activate(gen_n__0:n__plus:n__s:n__x3_7(n5_7)), activate(n__0)) →_IH
plus(gen_n__0:n__plus:n__s:n__x3_7(c6_7), activate(n__0)) →_R^Ω(1)
plus(gen_n__0:n__plus:n__s:n__x3_7(n5_7), n__0) →_R^Ω(1)
n__plus(gen_n__0:n__plus:n__s:n__x3_7(n5_7), n__0)

We have rt ∈ Ω(n¹) and sz ∈ O(n). Thus, we have irc_R ∈ Ω(n).
