Baham ko'rish
Klipbordga nusxa olish
72x-9\left(11x-19\right)=4\left(19-2x\right)
Tenglamaning ikkala tarafini 36 ga, 4,9 ning eng kichik karralisiga ko‘paytiring.
72x-99x+171=4\left(19-2x\right)
-9 ga 11x-19 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-27x+171=4\left(19-2x\right)
-27x ni olish uchun 72x va -99x ni birlashtirish.
-27x+171=76-8x
4 ga 19-2x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-27x+171+8x=76
8x ni ikki tarafga qo’shing.
-19x+171=76
-19x ni olish uchun -27x va 8x ni birlashtirish.
-19x=76-171
Ikkala tarafdan 171 ni ayirish.
-19x=-95
-95 olish uchun 76 dan 171 ni ayirish.
x=\frac{-95}{-19}
Ikki tarafini -19 ga bo‘ling.
x=5
5 ni olish uchun -95 ni -19 ga bo‘ling.
