2\left(4,5-2x\right)\left(1\times 7+4\right)=11
Tenglamaning ikkala tarafini 14 ga, 7,14 ning eng kichik karralisiga ko‘paytiring.
2\left(4,5-2x\right)\left(7+4\right)=11
7 hosil qilish uchun 1 va 7 ni ko'paytirish.
2\left(4,5-2x\right)\times 11=11
11 olish uchun 7 va 4'ni qo'shing.
22\left(4,5-2x\right)=11
22 hosil qilish uchun 2 va 11 ni ko'paytirish.
99-44x=11
22 ga 4,5-2x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-44x=11-99
Ikkala tarafdan 99 ni ayirish.
-44x=-88
-88 olish uchun 11 dan 99 ni ayirish.
x=\frac{-88}{-44}
Ikki tarafini -44 ga bo‘ling.
x=2
2 ni olish uchun -88 ni -44 ga bo‘ling.
