3x-1+7=8x-(3-2x) eching

$$3x-1+7=8x-(3-2x)$$

x uchun yechish

$$x = \frac{9}{7} = 1\frac{2}{7} \approx 1,285714286$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

6 olish uchun -1 va 7'ni qo'shing.

$$3x+6=8x-\left(3-2x\right)$$

3-2x teskarisini topish uchun har birining teskarisini toping.

$$3x+6=8x-3-\left(-2x\right)$$

-2x ning teskarisi 2x ga teng.

$$3x+6=8x-3+2x$$

10x ni olish uchun 8x va 2x ni birlashtirish.

$$3x+6=10x-3$$

Ikkala tarafdan 10x ni ayirish.

$$3x+6-10x=-3$$

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

$$-7x+6=-3$$

Ikkala tarafdan 6 ni ayirish.

$$-7x=-3-6$$

-9 olish uchun -3 dan 6 ni ayirish.

$$-7x=-9$$

Ikki tarafini -7 ga bo‘ling.

$$x=\frac{-9}{-7}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-9}{-7} kasrini \frac{9}{7} ga soddalashtirish mumkin.

$$x=\frac{9}{7}$$
