Proof step 36 from proof ac-dups-02 (previous step)

∀ class1, sk, val, val0, fis1, st. addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st) ⊦ addclass(class1, (fv + fis0) + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, (fv + fis0) + (sk × val) ' + fis1, st)

Proof step 35:
∀ class1, sk, val, val0, fis1, st. addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st) ⊦ addclass(class1, (fv ' + fis0) + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, (fv ' + fis0) + (sk × val) ' + fis1, st)
