\frac{2}{7}x=-\frac{3}{7}-\frac{1}{7}
Ikkala tarafdan \frac{1}{7} ni ayirish.
\frac{2}{7}x=\frac{-3-1}{7}
-\frac{3}{7} va \frac{1}{7} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.
\frac{2}{7}x=-\frac{4}{7}
-4 olish uchun -3 dan 1 ni ayirish.
x=-\frac{4}{7}\times \frac{7}{2}
Ikki tarafini \frac{7}{2} va teskari kasri \frac{2}{7} ga ko‘paytiring.
x=\frac{-4\times 7}{7\times 2}
Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{4}{7} ni \frac{7}{2} ga ko‘paytiring.
x=\frac{-4}{2}
Surat va maxrajdagi ikkala 7 ni qisqartiring.
x=-2
-2 ni olish uchun -4 ni 2 ga bo‘ling.
