| Ref | Expression |
|---|---|
| ineq1i.1 | ⊢ 𝐴 = 𝐵 |
| Ref | Expression |
|---|---|
| ineq1i | ⊢ (𝐴 ∩ 𝐶) = (𝐵 ∩ 𝐶) |
| Step | Hyp | Ref | Expression |
|---|---|---|---|
| 1 | ineq1i.1 | . 2 ⊢ 𝐴 = 𝐵 | |
| 2 | ineq1 4159 | . 2 ⊢ (𝐴 = 𝐵 → (𝐴 ∩ 𝐶) = (𝐵 ∩ 𝐶)) | |
| 3 | 1, 2 | ax-mp 5 | 1 ⊢ (𝐴 ∩ 𝐶) = (𝐵 ∩ 𝐶) |
