7-9x+3=3\left(-2x+4\right)+x-9
Tenglamaning ikkala tarafini 9 ga, 9,3 ning eng kichik karralisiga ko‘paytiring.
10-9x=3\left(-2x+4\right)+x-9
10 olish uchun 7 va 3'ni qo'shing.
10-9x=-6x+12+x-9
3 ga -2x+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10-9x=-5x+12-9
-5x ni olish uchun -6x va x ni birlashtirish.
10-9x=-5x+3
3 olish uchun 12 dan 9 ni ayirish.
10-9x+5x=3
5x ni ikki tarafga qo’shing.
10-4x=3
-4x ni olish uchun -9x va 5x ni birlashtirish.
-4x=3-10
Ikkala tarafdan 10 ni ayirish.
-4x=-7
-7 olish uchun 3 dan 10 ni ayirish.
x=\frac{-7}{-4}
Ikki tarafini -4 ga bo‘ling.
x=\frac{7}{4}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-7}{-4} kasrini \frac{7}{4} ga soddalashtirish mumkin.
