5x-18-\left(-x\right)>72
18-x teskarisini topish uchun har birining teskarisini toping.
5x-18+x>72
-x ning teskarisi x ga teng.
6x-18>72
6x ni olish uchun 5x va x ni birlashtirish.
6x>72+18
18 ni ikki tarafga qo’shing.
6x>90
90 olish uchun 72 va 18'ni qo'shing.
x>\frac{90}{6}
Ikki tarafini 6 ga bo‘ling. 6 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
x>15
15 ni olish uchun 90 ni 6 ga bo‘ling.
