\frac{2}{7}\times 3x+\frac{2}{7}\times 7=2-15x
\frac{2}{7} ga 3x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
\frac{2\times 3}{7}x+\frac{2}{7}\times 7=2-15x
\frac{2}{7}\times 3 ni yagona kasrga aylantiring.
\frac{6}{7}x+\frac{2}{7}\times 7=2-15x
6 hosil qilish uchun 2 va 3 ni ko'paytirish.
\frac{6}{7}x+2=2-15x
7 va 7 ni qisqartiring.
\frac{6}{7}x+2+15x=2
15x ni ikki tarafga qo’shing.
\frac{111}{7}x+2=2
\frac{111}{7}x ni olish uchun \frac{6}{7}x va 15x ni birlashtirish.
\frac{111}{7}x=2-2
Ikkala tarafdan 2 ni ayirish.
\frac{111}{7}x=0
0 olish uchun 2 dan 2 ni ayirish.
x=0
Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. \frac{111}{7} 0 ga teng bo‘lmasa, x 0 ga teng bo‘lishi kerak.
