Qisqa yechim qadamlari

-3y ni olish uchun -36y ni 12 ga bo‘ling.

$$-3y+\frac{18}{-27y}$$

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. -3y ni \frac{-27y}{-27y} marotabaga ko'paytirish.

$$\frac{-3y\left(-27\right)y}{-27y}+\frac{18}{-27y}$$

\frac{-3y\left(-27\right)y}{-27y} va \frac{18}{-27y} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-3y\left(-27\right)y+18}{-27y}$$

-3y\left(-27\right)y+18 ichidagi ko‘paytirishlarni bajaring.

$$\frac{81y^{2}+18}{-27y}$$

\frac{81y^{2}+18}{-27y} ichida hali faktorlanmagan ifodalarni faktorlang.
