2x=\frac{7}{20}+\frac{4}{5}
\frac{4}{5} ni ikki tarafga qo’shing.
2x=\frac{7}{20}+\frac{16}{20}
20 va 5 ning eng kichik umumiy karralisi 20 ga teng. \frac{7}{20} va \frac{4}{5} ni 20 maxraj bilan kasrlarga aylantirib oling.
2x=\frac{7+16}{20}
\frac{7}{20} va \frac{16}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.
2x=\frac{23}{20}
23 olish uchun 7 va 16'ni qo'shing.
x=\frac{\frac{23}{20}}{2}
Ikki tarafini 2 ga bo‘ling.
x=\frac{23}{20\times 2}
\frac{\frac{23}{20}}{2} ni yagona kasrga aylantiring.
x=\frac{23}{40}
40 hosil qilish uchun 20 va 2 ni ko'paytirish.
