16x=120x\times \frac{1}{8}+120
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 120x ga, 15,8,x ning eng kichik karralisiga ko‘paytiring.
16x=\frac{120}{8}x+120
\frac{120}{8} hosil qilish uchun 120 va \frac{1}{8} ni ko'paytirish.
16x=15x+120
15 ni olish uchun 120 ni 8 ga bo‘ling.
16x-15x=120
Ikkala tarafdan 15x ni ayirish.
x=120
x ni olish uchun 16x va -15x ni birlashtirish.
