y+4=-2/5(x-1) eching

$$y + 4 = - \frac { 2 } { 5 } ( x - 1 )$$

x uchun yechish

$$x=-\frac{5y}{2}-9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-\frac{2}{5} ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y+4=-\frac{2}{5}x+\frac{2}{5}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-\frac{2}{5}x+\frac{2}{5}=y+4$$

Ikkala tarafdan \frac{2}{5} ni ayirish.

$$-\frac{2}{5}x=y+4-\frac{2}{5}$$

\frac{18}{5} olish uchun 4 dan \frac{2}{5} ni ayirish.

$$-\frac{2}{5}x=y+\frac{18}{5}$$

Tenglamaning ikki tarafini -\frac{2}{5} ga bo'lish, bu kasrni qaytarish orqali ikkala tarafga ko'paytirish bilan aynidir.

$$\frac{-\frac{2}{5}x}{-\frac{2}{5}}=\frac{y+\frac{18}{5}}{-\frac{2}{5}}$$

-\frac{2}{5} ga bo'lish -\frac{2}{5} ga ko'paytirishni bekor qiladi.

$$x=\frac{y+\frac{18}{5}}{-\frac{2}{5}}$$

y+\frac{18}{5} ni -\frac{2}{5} ga bo'lish y+\frac{18}{5} ga k'paytirish -\frac{2}{5} ga qaytarish.

$$x=-\frac{5y}{2}-9$$

y uchun yechish

$$y=\frac{-2x-18}{5}$$

Yechim qadamlari

-\frac{2}{5} ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y+4=-\frac{2}{5}x+\frac{2}{5}$$

Ikkala tarafdan 4 ni ayirish.

$$y=-\frac{2}{5}x+\frac{2}{5}-4$$

-\frac{18}{5} olish uchun \frac{2}{5} dan 4 ni ayirish.

$$y=-\frac{2}{5}x-\frac{18}{5}$$
