Theorem lmodvnegid 21055

Description: Addition of a vector with its negative. (Contributed by NM, 18-Apr-2014.) (Revised by Mario Carneiro, 19-Jun-2014.)

**Hypotheses**
Ref	Expression
lmodvnegid.v	⊢ 𝑉 = (Base‘𝑊)
lmodvnegid.p	⊢ + = (+_g‘𝑊)
lmodvnegid.z	⊢ 0 = (0_g‘𝑊)
lmodvnegid.n	⊢ 𝑁 = (inv_g‘𝑊)

**Assertion**
Ref	Expression
lmodvnegid	⊢ ((𝑊 ∈ LMod ∧ 𝑋 ∈ 𝑉) → (𝑋 + (𝑁‘𝑋)) = 0 )
