y+1=-1/2(x+7) eching

$$y + 1 = - \frac { 1 } { 2 } ( x + 7 )$$

x uchun yechish

$$x=-2y-9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-\frac{1}{2} ga x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y+1=-\frac{1}{2}x-\frac{7}{2}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-\frac{1}{2}x-\frac{7}{2}=y+1$$

\frac{7}{2} ni ikki tarafga qo’shing.

$$-\frac{1}{2}x=y+1+\frac{7}{2}$$

\frac{9}{2} olish uchun 1 va \frac{7}{2}'ni qo'shing.

$$-\frac{1}{2}x=y+\frac{9}{2}$$

Ikkala tarafini -2 ga ko‘paytiring.

$$\frac{-\frac{1}{2}x}{-\frac{1}{2}}=\frac{y+\frac{9}{2}}{-\frac{1}{2}}$$

-\frac{1}{2} ga bo'lish -\frac{1}{2} ga ko'paytirishni bekor qiladi.

$$x=\frac{y+\frac{9}{2}}{-\frac{1}{2}}$$

y+\frac{9}{2} ni -\frac{1}{2} ga bo'lish y+\frac{9}{2} ga k'paytirish -\frac{1}{2} ga qaytarish.

$$x=-2y-9$$

y uchun yechish

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

Yechim qadamlari

-\frac{1}{2} ga x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y+1=-\frac{1}{2}x-\frac{7}{2}$$

Ikkala tarafdan 1 ni ayirish.

$$y=-\frac{1}{2}x-\frac{7}{2}-1$$

-\frac{9}{2} olish uchun -\frac{7}{2} dan 1 ni ayirish.

$$y=-\frac{1}{2}x-\frac{9}{2}$$
