Theorem lvecdim 21155

Description: The dimension theorem for vector spaces: any two bases of the same vector space are equinumerous. Proven by using lssacsex 21142 and lbsacsbs 21154 to show that being a basis for a vector space is equivalent to being a basis for the associated algebraic closure system, and then using acsexdimd 18525. (Contributed by David Moews, 1-May-2017.)

**Hypothesis**
Ref	Expression
lvecdim.1	⊢ 𝐽 = (LBasis‘𝑊)

**Assertion**
Ref	Expression
lvecdim	⊢ ((𝑊 ∈ LVec ∧ 𝑆 ∈ 𝐽 ∧ 𝑇 ∈ 𝐽) → 𝑆 ≈ 𝑇)

Proof of Theorem lvecdim Dummy variables 𝑥 𝑦 𝑧 are mutually distinct and distinct from all other variables.
