-11n=-\left(n+18\right)-14\left(n-5\right)
-11n ni olish uchun -19n va 8n ni birlashtirish.
-11n=-n-18-14\left(n-5\right)
n+18 teskarisini topish uchun har birining teskarisini toping.
-11n=-n-18-14n+70
-14 ga n-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-11n=-15n-18+70
-15n ni olish uchun -n va -14n ni birlashtirish.
-11n=-15n+52
52 olish uchun -18 va 70'ni qo'shing.
-11n+15n=52
15n ni ikki tarafga qo’shing.
4n=52
4n ni olish uchun -11n va 15n ni birlashtirish.
n=\frac{52}{4}
Ikki tarafini 4 ga bo‘ling.
n=13
13 ni olish uchun 52 ni 4 ga bo‘ling.
