Proof step 7 from proof rm-vl-in-before-h (previous step)

eq-entry(n, lref) ∈ (lref0 = lref ⊃ q0 - lref;eq-entry(m, lref0) ' + (q0 - lref)), ∀ n, lref. ¬ eq-entry(n, lref) ∈ q0 - lref ⊦

Heuristic cut applied rule cut formula

And obtained the following new goals

Proof step 8:
lref0 = lref, eq-entry(n, lref) ∈ (lref0 = lref ⊃ q0 - lref;eq-entry(m, lref0) ' + (q0 - lref)), ∀ n, lref. ¬ eq-entry(n, lref) ∈ q0 - lref ⊦
Proof step 10:
eq-entry(n, lref) ∈ (lref0 = lref ⊃ q0 - lref;eq-entry(m, lref0) ' + (q0 - lref)), ∀ n, lref. ¬ eq-entry(n, lref) ∈ q0 - lref ⊦ lref0 = lref

Rule argument

fma: lref0 = lref

Additional information

Used formulas: lref0 = lref
