18\left(-x+30\right)=86-0
x qiymati 30 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini -x+30 ga ko'paytirish.
-18x+540=86-0
18 ga -x+30 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-18x+540=86
86 olish uchun 86 dan 0 ni ayirish.
-18x=86-540
Ikkala tarafdan 540 ni ayirish.
-18x=-454
-454 olish uchun 86 dan 540 ni ayirish.
x=\frac{-454}{-18}
Ikki tarafini -18 ga bo‘ling.
x=\frac{227}{9}
\frac{-454}{-18} ulushini -2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
