7-4x=22-9x-27
-9 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
7-4x=-5-9x
-5 olish uchun 22 dan 27 ni ayirish.
7-4x+9x=-5
9x ni ikki tarafga qo’shing.
7+5x=-5
5x ni olish uchun -4x va 9x ni birlashtirish.
5x=-5-7
Ikkala tarafdan 7 ni ayirish.
5x=-12
-12 olish uchun -5 dan 7 ni ayirish.
x=\frac{-12}{5}
Ikki tarafini 5 ga bo‘ling.
x=-\frac{12}{5}
\frac{-12}{5} kasri manfiy belgini olib tashlash bilan -\frac{12}{5} sifatida qayta yozilishi mumkin.
