Description: Equality theorem for 𝐶-coset of 𝐴 and 𝐶-coset of 𝐵, inference version. (Contributed by Peter Mazsa, 11-May-2021.)

Hypothesis

Ref	Expression
eceq1i.1	⊢ 𝐴 = 𝐵

Assertion

Ref	Expression
eceq1i	⊢ [𝐴]𝐶 = [𝐵]𝐶

Proof of Theorem eceq1i

Step	Hyp	Ref	Expression
1		eceq1i.1	. 2 ⊢ 𝐴 = 𝐵
2		eceq1 8739	. 2 ⊢ (𝐴 = 𝐵 → [𝐴]𝐶 = [𝐵]𝐶)
3	1, 2	ax-mp 5	1 ⊢ [𝐴]𝐶 = [𝐵]𝐶
