Proof step 4 from proof neq-7-not-even (previous step)

2 * i ≠ 2 * ~5 + 1, ~7 = 2 * i ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
~7 = 2 * i ⊦

Rule argument

Additional information

Used simplifier rules: associativity: ⊦ i * j * j0 = (i * j) * j0;%commutativity: ⊦ i * j = j * i;%neq-9-not-even: ⊦ ~9 ≠ 2 * i;%add-c: ⊦ i + j = j + i; from specification int-basic2%add-a: ⊦ i + j + i0 = (i + j) + i0; from specification int-basic2
