Theorem ssmxidl 32852

Description: Let 𝑅 be a ring, and let 𝐼 be a proper ideal of 𝑅. Then there is a maximal ideal of 𝑅 containing 𝐼. (Contributed by Thierry Arnoux, 10-Apr-2024.)

**Hypothesis**
Ref	Expression
ssmxidl.1	⊢ 𝐵 = (Base‘𝑅)

**Assertion**
Ref	Expression
ssmxidl	⊢ ((𝑅 ∈ Ring ∧ 𝐼 ∈ (LIdeal‘𝑅) ∧ 𝐼 ≠ 𝐵) → ∃𝑚 ∈ (MaxIdeal‘𝑅)𝐼 ⊆ 𝑚)

Distinct variable groups: 𝐵,𝑚 𝑚,𝐼 𝑅,𝑚

Proof of Theorem ssmxidl Dummy variables 𝑗 𝑝 𝑧 𝑘 are mutually distinct and distinct from all other variables.
