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

$$- ( 1 - 2 x ) - 5 x \leq - ( 1 + x ) - 4$$

x uchun yechish

$$x\geq 2$$

Yechim qadamlari

1-2x teskarisini topish uchun har birining teskarisini toping.

$$-1-\left(-2x\right)-5x\leq -\left(1+x\right)-4$$

-2x ning teskarisi 2x ga teng.

$$-1+2x-5x\leq -\left(1+x\right)-4$$

-3x ni olish uchun 2x va -5x ni birlashtirish.

$$-1-3x\leq -\left(1+x\right)-4$$

1+x teskarisini topish uchun har birining teskarisini toping.

$$-1-3x\leq -1-x-4$$

-5 olish uchun -1 dan 4 ni ayirish.

$$-1-3x\leq -5-x$$

x ni ikki tarafga qo’shing.

$$-1-3x+x\leq -5$$

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

$$-1-2x\leq -5$$

1 ni ikki tarafga qo’shing.

$$-2x\leq -5+1$$

-4 olish uchun -5 va 1'ni qo'shing.

$$-2x\leq -4$$

Ikki tarafini -2 ga bo‘ling. -2 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$x\geq \frac{-4}{-2}$$

2 ni olish uchun -4 ni -2 ga bo‘ling.

$$x\geq 2$$
