\frac{2}{3}x=-\frac{3}{8}-\frac{1}{2}
Ikkala tarafdan \frac{1}{2} ni ayirish.
\frac{2}{3}x=-\frac{3}{8}-\frac{4}{8}
8 va 2 ning eng kichik umumiy karralisi 8 ga teng. -\frac{3}{8} va \frac{1}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.
\frac{2}{3}x=\frac{-3-4}{8}
-\frac{3}{8} va \frac{4}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
\frac{2}{3}x=-\frac{7}{8}
-7 olish uchun -3 dan 4 ni ayirish.
x=-\frac{7}{8}\times \frac{3}{2}
Ikki tarafini \frac{3}{2} va teskari kasri \frac{2}{3} ga ko‘paytiring.
x=\frac{-7\times 3}{8\times 2}
Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{7}{8} ni \frac{3}{2} ga ko‘paytiring.
x=\frac{-21}{16}
\frac{-7\times 3}{8\times 2} kasridagi ko‘paytirishlarni bajaring.
x=-\frac{21}{16}
\frac{-21}{16} kasri manfiy belgini olib tashlash bilan -\frac{21}{16} sifatida qayta yozilishi mumkin.
