Hypothesis

Ref	Expression
erALTVeq1d.1	⊢ (𝜑 → 𝑅 = 𝑆)

Assertion

Ref	Expression
erALTVeq1d	⊢ (𝜑 → (𝑅 ErALTV 𝐴 ↔ 𝑆 ErALTV 𝐴))

Proof of Theorem erALTVeq1d

Step	Hyp	Ref	Expression
1		erALTVeq1d.1	. 2 ⊢ (𝜑 → 𝑅 = 𝑆)
2		erALTVeq1 39780	. 2 ⊢ (𝑅 = 𝑆 → (𝑅 ErALTV 𝐴 ↔ 𝑆 ErALTV 𝐴))
3	1, 2	syl 18	1 ⊢ (𝜑 → (𝑅 ErALTV 𝐴 ↔ 𝑆 ErALTV 𝐴))
