4x+2\leq 7-x-4
x+4 teskarisini topish uchun har birining teskarisini toping.
4x+2\leq 3-x
3 olish uchun 7 dan 4 ni ayirish.
4x+2+x\leq 3
x ni ikki tarafga qo’shing.
5x+2\leq 3
5x ni olish uchun 4x va x ni birlashtirish.
5x\leq 3-2
Ikkala tarafdan 2 ni ayirish.
5x\leq 1
1 olish uchun 3 dan 2 ni ayirish.
x\leq \frac{1}{5}
Ikki tarafini 5 ga bo‘ling. 5 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
