Proof step 21 from proof ac-dups-02 (previous step)

fs = mkfs(class, ty, fieldvar), ∀ class1, sk, val, val0, fis1, st. addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st) ⊦ addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st), class = class1

Proof step 20:
∀ class1, sk, val, val0, fis1, st. addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st) ⊦ addclass(class1, fis0 + (sk × val) ' + (sk × val0) ' + fis1, st) = addclass(class1, fis0 + (sk × val) ' + fis1, st), class = class1
