Description: Equality theorem for the range Cartesian product, inference form. (Contributed by Peter Mazsa, 16-Dec-2020.)

Hypothesis

Ref	Expression
xrneq2i.1	⊢ 𝐴 = 𝐵

Assertion

Ref	Expression
xrneq2i	⊢ (𝐶 ⋉ 𝐴) = (𝐶 ⋉ 𝐵)

Proof of Theorem xrneq2i

Step	Hyp	Ref	Expression
1		xrneq2i.1	. 2 ⊢ 𝐴 = 𝐵
2		xrneq2 38895	. 2 ⊢ (𝐴 = 𝐵 → (𝐶 ⋉ 𝐴) = (𝐶 ⋉ 𝐵))
3	1, 2	ax-mp 5	1 ⊢ (𝐶 ⋉ 𝐴) = (𝐶 ⋉ 𝐵)
