2x-1/7-x+6/5=-1 eching

$$\frac { 2 x - 1 } { 7 } - \frac { x + 6 } { 5 } = - 1$$

x uchun yechish

$$x=4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 35 ga, 7,5 ning eng kichik karralisiga ko‘paytiring.

$$5\left(2x-1\right)-7\left(x+6\right)=-35$$

5 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$10x-5-7\left(x+6\right)=-35$$

-7 ga x+6 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$10x-5-7x-42=-35$$

3x ni olish uchun 10x va -7x ni birlashtirish.

$$3x-5-42=-35$$

-47 olish uchun -5 dan 42 ni ayirish.

$$3x-47=-35$$

47 ni ikki tarafga qo’shing.

$$3x=-35+47$$

12 olish uchun -35 va 47'ni qo'shing.

$$3x=12$$

Ikki tarafini 3 ga bo‘ling.

$$x=\frac{12}{3}$$

4 ni olish uchun 12 ni 3 ga bo‘ling.

$$x=4$$
