Hypotheses

Ref	Expression
xrneq12i.1	⊢ 𝐴 = 𝐵
xrneq12i.2	⊢ 𝐶 = 𝐷

Assertion

Ref	Expression
xrneq12i	⊢ (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷)

Proof of Theorem xrneq12i

Step	Hyp	Ref	Expression
1		xrneq12i.1	. 2 ⊢ 𝐴 = 𝐵
2		xrneq12i.2	. 2 ⊢ 𝐶 = 𝐷
3		xrneq12 39079	. 2 ⊢ ((𝐴 = 𝐵 ∧ 𝐶 = 𝐷) → (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷))
4	1, 2, 3	mp2an 704	1 ⊢ (𝐴 ⋉ 𝐶) = (𝐵 ⋉ 𝐷)
