Let x0 of type ι be given.
Let x1 of type ι → ι be given.
Let x2 of type ι → ι be given.
Let x3 of type ι → ι be given.
Let x4 of type ι → ι be given.
Let x5 of type ι be given.
Assume H0:
∀ x6 . prim1 x6 x0 ⟶ x1 x6 = x2 x6.
Assume H1:
∀ x6 . prim1 x6 x0 ⟶ x3 x6 = x4 x6.
Apply unknownprop_075a71193d04eff3936ee7246a228619e3dbe0ea2b9d96d40e9b467470ee4a92 with
x0,
x1,
x2.
The subproof is completed by applying H0.
