2-5(2y+4)-(-3y-1)=-(y+5) eching

$$2 - 5 ( 2 y + 4 ) - ( - 3 y - 1 ) = - ( y + 5 )$$

y uchun yechish

$$y=-2$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-5 ga 2y+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2-10y-20-\left(-3y-1\right)=-\left(y+5\right)$$

-18 olish uchun 2 dan 20 ni ayirish.

$$-18-10y-\left(-3y-1\right)=-\left(y+5\right)$$

-3y-1 teskarisini topish uchun har birining teskarisini toping.

$$-18-10y-\left(-3y\right)-\left(-1\right)=-\left(y+5\right)$$

-3y ning teskarisi 3y ga teng.

$$-18-10y+3y-\left(-1\right)=-\left(y+5\right)$$

-1 ning teskarisi 1 ga teng.

$$-18-10y+3y+1=-\left(y+5\right)$$

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

$$-18-7y+1=-\left(y+5\right)$$

-17 olish uchun -18 va 1'ni qo'shing.

$$-17-7y=-\left(y+5\right)$$

y+5 teskarisini topish uchun har birining teskarisini toping.

$$-17-7y=-y-5$$

y ni ikki tarafga qo’shing.

$$-17-7y+y=-5$$

-6y ni olish uchun -7y va y ni birlashtirish.

$$-17-6y=-5$$

17 ni ikki tarafga qo’shing.

$$-6y=-5+17$$

12 olish uchun -5 va 17'ni qo'shing.

$$-6y=12$$

Ikki tarafini -6 ga bo‘ling.

$$y=\frac{12}{-6}$$

-2 ni olish uchun 12 ni -6 ga bo‘ling.

$$y=-2$$
