545n-425n\geq -252
Ikkala tarafdan 425n ni ayirish.
120n\geq -252
120n ni olish uchun 545n va -425n ni birlashtirish.
n\geq \frac{-252}{120}
Ikki tarafini 120 ga bo‘ling. 120 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
n\geq -\frac{21}{10}
\frac{-252}{120} ulushini 12 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
