4\left(9x-1\right)-13\left(5x-8\right)=52x+312
Tenglamaning ikkala tarafini 52 ga, 13,4 ning eng kichik karralisiga ko‘paytiring.
36x-4-13\left(5x-8\right)=52x+312
4 ga 9x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
36x-4-65x+104=52x+312
-13 ga 5x-8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-29x-4+104=52x+312
-29x ni olish uchun 36x va -65x ni birlashtirish.
-29x+100=52x+312
100 olish uchun -4 va 104'ni qo'shing.
-29x+100-52x=312
Ikkala tarafdan 52x ni ayirish.
-81x+100=312
-81x ni olish uchun -29x va -52x ni birlashtirish.
-81x=312-100
Ikkala tarafdan 100 ni ayirish.
-81x=212
212 olish uchun 312 dan 100 ni ayirish.
x=\frac{212}{-81}
Ikki tarafini -81 ga bo‘ling.
x=-\frac{212}{81}
\frac{212}{-81} kasri manfiy belgini olib tashlash bilan -\frac{212}{81} sifatida qayta yozilishi mumkin.
