Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini -5z+8 ga ko'paytirish.

$$y\left(-5z+8\right)=8-5t$$

y ga -5z+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-5yz+8y=8-5t$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$8-5t=-5yz+8y$$

Ikkala tarafdan 8 ni ayirish.

$$-5t=-5yz+8y-8$$

Ikki tarafini -5 ga bo‘ling.

$$\frac{-5t}{-5}=\frac{-5yz+8y-8}{-5}$$

-5 ga bo'lish -5 ga ko'paytirishni bekor qiladi.

$$t=\frac{-5yz+8y-8}{-5}$$

-5yz+8y-8 ni -5 ga bo'lish.

$$t=yz-\frac{8y}{5}+\frac{8}{5}$$

y uchun yechish

$$y=-\frac{5t-8}{8-5z}$$

$$z\neq \frac{8}{5}$$
