3\left(3x-5\right)+2=x-1
Tenglamaning ikkala tarafini 6 ga, 2,3,6 ning eng kichik karralisiga ko‘paytiring.
9x-15+2=x-1
3 ga 3x-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9x-13=x-1
-13 olish uchun -15 va 2'ni qo'shing.
9x-13-x=-1
Ikkala tarafdan x ni ayirish.
8x-13=-1
8x ni olish uchun 9x va -x ni birlashtirish.
8x=-1+13
13 ni ikki tarafga qo’shing.
8x=12
12 olish uchun -1 va 13'ni qo'shing.
x=\frac{12}{8}
Ikki tarafini 8 ga bo‘ling.
x=\frac{3}{2}
\frac{12}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
