Proof step 36 from proof odd-add (previous step)

2 * m0 = 2 * m2 + n ⊦ 2 * (m0 - m2) = n

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

Additional information

Used simplifier rules: lels-01: ⊦ ¬ m ≤ n ↔ n < m; from specification nat%mult-a: ⊦ m0 * m * n = (m0 * m) * n; from specification nat-mult%mult-c: ⊦ m * n = n * m; from specification nat-mult%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic2%c: ⊦ m + n = n + m; from specification nat-basic2%two-succ-06: ⊦ 2 * m = 2 * n + m0 → ¬ m < n; from specification nat-mult%n ≤ m ⊦ n0 = m - n ↔ m = n0 + n; (elim) Used terms: m0, m2, n0
