5\times 3+10x\left(-\frac{7}{5}\right)=2\times 4+10x\left(-\frac{5}{2}\right)
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 10x ga, 2x,5,5x,2 ning eng kichik karralisiga ko‘paytiring.
15+10x\left(-\frac{7}{5}\right)=2\times 4+10x\left(-\frac{5}{2}\right)
15 hosil qilish uchun 5 va 3 ni ko'paytirish.
15-14x=2\times 4+10x\left(-\frac{5}{2}\right)
-14 hosil qilish uchun 10 va -\frac{7}{5} ni ko'paytirish.
15-14x=8+10x\left(-\frac{5}{2}\right)
8 hosil qilish uchun 2 va 4 ni ko'paytirish.
15-14x=8-25x
-25 hosil qilish uchun 10 va -\frac{5}{2} ni ko'paytirish.
15-14x+25x=8
25x ni ikki tarafga qo’shing.
15+11x=8
11x ni olish uchun -14x va 25x ni birlashtirish.
11x=8-15
Ikkala tarafdan 15 ni ayirish.
11x=-7
-7 olish uchun 8 dan 15 ni ayirish.
x=\frac{-7}{11}
Ikki tarafini 11 ga bo‘ling.
x=-\frac{7}{11}
\frac{-7}{11} kasri manfiy belgini olib tashlash bilan -\frac{7}{11} sifatida qayta yozilishi mumkin.
