Quyidagi amaldan Δ - ■ ni toping.
  1. -13
  2. 9
  3. -9
  4. 13

📝 Detailed explanation

Jadvalning birinchi va ikkinchi qator kesishmasidan tenglama tuzamiz: -3 + Δ = -5 => Δ = -5 + 3 => Δ = -2.
Endi ikkinchi ustun va uchinchi qator kesishmasidan ■ ni topamiz: Δ + (-9) = ■ => -2 - 9 = -11. Demak, ■ = -11.
So'ralgan ifodani hisoblaymiz: Δ - ■ = -2 - (-11) = -2 + 11 = 9.
