**Assertion**
Ref	Expression
sge0xaddlem1	⊢ (𝜑 → ((Σ^{^}‘(𝑘 ∈ 𝐴 ↦ 𝐵)) + (Σ^{^}‘(𝑘 ∈ 𝐴 ↦ 𝐶))) ≤ (sup(ran (𝑥 ∈ (𝒫 𝐴 ∩ Fin) ↦ Σ𝑘 ∈ 𝑥 (𝐵 + 𝐶)), ℝ^*, < ) +_𝑒 𝐸))

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

Proof of Theorem sge0xaddlem1 Dummy variables 𝑦 𝑧 are mutually distinct and distinct from all other variables.
