x=-\frac{1}{3}+\frac{3}{7}
\frac{3}{7} ni ikki tarafga qo’shing.
x=-\frac{7}{21}+\frac{9}{21}
3 va 7 ning eng kichik umumiy karralisi 21 ga teng. -\frac{1}{3} va \frac{3}{7} ni 21 maxraj bilan kasrlarga aylantirib oling.
x=\frac{-7+9}{21}
-\frac{7}{21} va \frac{9}{21} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
x=\frac{2}{21}
2 olish uchun -7 va 9'ni qo'shing.
