3\left(-x\right)=2\left(-x\right)-2\times 2x
Tenglamaning ikkala tarafini 6 ga, 2,3 ning eng kichik karralisiga ko‘paytiring.
3\left(-x\right)=2\left(-x\right)-4x
-4 hosil qilish uchun -2 va 2 ni ko'paytirish.
3\left(-x\right)-2\left(-x\right)=-4x
Ikkala tarafdan 2\left(-x\right) ni ayirish.
-x=-4x
-x ni olish uchun 3\left(-x\right) va -2\left(-x\right) ni birlashtirish.
-x+4x=0
4x ni ikki tarafga qo’shing.
3x=0
3x ni olish uchun -x va 4x ni birlashtirish.
x=0
Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. 3 0 ga teng bo‘lmasa, x 0 ga teng bo‘lishi kerak.
