Tengliklardan foydalanib noma'lumlarni toping: 12 × Δ = 72, Δ × ω = 882 va ω ÷ 7 = ■. U holda ω − ■ + Δ ning qiymatini hisoblang.

📝 Detailed explanation

Birinchi tenglikdan Δ = 72 ÷ 12 = 6 kelib chiqadi. Ikkinchi tenglikdan 6 × ω = 882 ⇒ ω = 147. Uchinchisidan ■ = 147 ÷ 7 = 21. So'ralgan ifoda: 147 − 21 + 6 = 132.
