x-7y+17=0 eching

$$x-7y+17=0$$

x uchun yechish

$$x=7y-17$$

Yechim qadamlari

7y ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$x+17=7y$$

Ikkala tarafdan 17 ni ayirish.

$$x=7y-17$$

y uchun yechish

$$y=\frac{x+17}{7}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan x ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-7y+17=-x$$

Ikkala tarafdan 17 ni ayirish.

$$-7y=-x-17$$

Ikki tarafini -7 ga bo‘ling.

$$\frac{-7y}{-7}=\frac{-x-17}{-7}$$

-7 ga bo'lish -7 ga ko'paytirishni bekor qiladi.

$$y=\frac{-x-17}{-7}$$

-x-17 ni -7 ga bo'lish.

$$y=\frac{x+17}{7}$$
