\left(x+2\right)\times 2=\left(3x-1\right)\times 3
x qiymati -2,\frac{1}{3} qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(3x-1\right)\left(x+2\right) ga, 3x-1,x+2 ning eng kichik karralisiga ko‘paytiring.
2x+4=\left(3x-1\right)\times 3
x+2 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+4=9x-3
3x-1 ga 3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+4-9x=-3
Ikkala tarafdan 9x ni ayirish.
-7x+4=-3
-7x ni olish uchun 2x va -9x ni birlashtirish.
-7x=-3-4
Ikkala tarafdan 4 ni ayirish.
-7x=-7
-7 olish uchun -3 dan 4 ni ayirish.
x=\frac{-7}{-7}
Ikki tarafini -7 ga bo‘ling.
x=1
1 ni olish uchun -7 ni -7 ga bo‘ling.
