Theorem itgaddnc 36634

Description: Choice-free analogue of itgadd 25349. (Contributed by Brendan Leahy, 11-Nov-2017.)

**Hypotheses**
Ref	Expression
ibladdnc.1	⊢ ((𝜑 ∧ 𝑥 ∈ 𝐴) → 𝐵 ∈ 𝑉)
ibladdnc.2	⊢ (𝜑 → (𝑥 ∈ 𝐴 ↦ 𝐵) ∈ 𝐿¹)
ibladdnc.3	⊢ ((𝜑 ∧ 𝑥 ∈ 𝐴) → 𝐶 ∈ 𝑉)
ibladdnc.4	⊢ (𝜑 → (𝑥 ∈ 𝐴 ↦ 𝐶) ∈ 𝐿¹)
ibladdnc.m	⊢ (𝜑 → (𝑥 ∈ 𝐴 ↦ (𝐵 + 𝐶)) ∈ MblFn)

**Assertion**
Ref	Expression
itgaddnc	⊢ (𝜑 → ∫𝐴(𝐵 + 𝐶) d𝑥 = (∫𝐴𝐵 d𝑥 + ∫𝐴𝐶 d𝑥))

Distinct variable groups: 𝑥,𝐴 𝑥,𝑉 𝜑,𝑥 Allowed substitution hints: 𝐵(𝑥) 𝐶(𝑥)

Proof of Theorem itgaddnc Dummy variable 𝑦 is distinct from all other variables.
