Theorem mppsthm

Description: A provable pre-statement is a theorem. (Contributed by Mario Carneiro, 18-Jul-2016)

Ref Expression
Hypotheses mppsthm.j ⊢ J = mPPSt ⁡ T
mppsthm.u ⊢ U = mThm ⁡ T
Assertion mppsthm ⊢ J ⊆ U

Proof

Step Hyp Ref Expression
1 mppsthm.j ⊢ J = mPPSt ⁡ T
2 mppsthm.u ⊢ U = mThm ⁡ T
3 eqid ⊢ mStRed ⁡ T ⁡ x = mStRed ⁡ T ⁡ x
4 eqid ⊢ mStRed ⁡ T = mStRed ⁡ T
5 4 1 2 mthmi ⊢ x ∈ J ∧ mStRed ⁡ T ⁡ x = mStRed ⁡ T ⁡ x → x ∈ U
6 3 5 mpan2 ⊢ x ∈ J → x ∈ U
7 6 ssriv ⊢ J ⊆ U
