Theorem prnc 38061

Description: A principal ideal (an ideal generated by one element) in a commutative ring. (Contributed by Jeff Madsen, 10-Jun-2010.)

**Hypotheses**
Ref	Expression
prnc.1	⊢ 𝐺 = (1^st ‘𝑅)
prnc.2	⊢ 𝐻 = (2^nd ‘𝑅)
prnc.3	⊢ 𝑋 = ran 𝐺

**Assertion**
Ref	Expression
prnc	⊢ ((𝑅 ∈ CRingOps ∧ 𝐴 ∈ 𝑋) → (𝑅 IdlGen {𝐴}) = {𝑥 ∈ 𝑋 ∣ ∃𝑦 ∈ 𝑋 𝑥 = (𝑦𝐻𝐴)})

Distinct variable groups: 𝑥,𝑅,𝑦 𝑥,𝑋,𝑦 𝑥,𝐺,𝑦 𝑥,𝐻,𝑦 𝑥,𝐴,𝑦

Proof of Theorem prnc Dummy variables 𝑗 𝑢 𝑣 𝑤 𝑟 𝑠 are mutually distinct and distinct from all other variables.
