E=-[-3x+(-x-{2y-3})]+{-(2x+y)+(-x-3)+2-[x+y]} eching

$$E = - [ - 3 x + ( - x - \{ 2 y - 3 \} ) ] + \{ - ( 2 x + y ) + ( - x - 3 ) + 2 - [ x + y ] \}$$

E uchun yechish

$$E=-4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$E=-\left(-3x-x-2y+3\right)-\left(2x+y\right)-x-3+2-\left(x+y\right)$$

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

$$E=3x-\left(-x\right)+2y-3-\left(2x+y\right)-x-3+2-\left(x+y\right)$$

2x+y teskarisini topish uchun har birining teskarisini toping.

$$E=3x-\left(-x\right)+2y-3-2x-y-x-3+2-\left(x+y\right)$$

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

$$E=x-\left(-x\right)+2y-3-y-x-3+2-\left(x+y\right)$$

y ni olish uchun 2y va -y ni birlashtirish.

$$E=x-\left(-x\right)+y-3-x-3+2-\left(x+y\right)$$

-6 olish uchun -3 dan 3 ni ayirish.

$$E=x-\left(-x\right)+y-6-x+2-\left(x+y\right)$$

-4 olish uchun -6 va 2'ni qo'shing.

$$E=x-\left(-x\right)+y-4-x-\left(x+y\right)$$

x+y teskarisini topish uchun har birining teskarisini toping.

$$E=x-\left(-x\right)+y-4-x-x-y$$

0 ni olish uchun x va -x ni birlashtirish.

$$E=-\left(-x\right)+y-4-x-y$$

0 ni olish uchun y va -y ni birlashtirish.

$$E=-\left(-x\right)-4-x$$

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

$$E=x-4-x$$

0 ni olish uchun x va -x ni birlashtirish.

$$E=-4$$
