3\left(6y-5\right)=\left(y+2\right)\left(-4\right)
y qiymati -2 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 3\left(y+2\right) ga, y+2,3 ning eng kichik karralisiga ko‘paytiring.
18y-15=\left(y+2\right)\left(-4\right)
3 ga 6y-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
18y-15=-4y-8
y+2 ga -4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
18y-15+4y=-8
4y ni ikki tarafga qo’shing.
22y-15=-8
22y ni olish uchun 18y va 4y ni birlashtirish.
22y=-8+15
15 ni ikki tarafga qo’shing.
22y=7
7 olish uchun -8 va 15'ni qo'shing.
y=\frac{7}{22}
Ikki tarafini 22 ga bo‘ling.
