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

$$4(-x-1)+5x-2=-2x-x$$

x uchun yechish

$$x = \frac{3}{2} = 1\frac{1}{2} = 1,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$4\left(-x\right)-4+5x-2=-2x-x$$

-6 olish uchun -4 dan 2 ni ayirish.

$$4\left(-x\right)-6+5x=-2x-x$$

-3x ni olish uchun -2x va -x ni birlashtirish.

$$4\left(-x\right)-6+5x=-3x$$

3x ni ikki tarafga qo’shing.

$$4\left(-x\right)-6+5x+3x=0$$

8x ni olish uchun 5x va 3x ni birlashtirish.

$$4\left(-x\right)-6+8x=0$$

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

$$4\left(-x\right)+8x=6$$

-4 hosil qilish uchun 4 va -1 ni ko'paytirish.

$$-4x+8x=6$$

4x ni olish uchun -4x va 8x ni birlashtirish.

$$4x=6$$

Ikki tarafini 4 ga bo‘ling.

$$x=\frac{6}{4}$$

\frac{6}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{3}{2}$$
