(21/10-6/10)x=60 eching

$$( \frac { 21 } { 10 } - \frac { 6 } { 10 } ) x = 60$$

x uchun yechish

$$x=40$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{6}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\left(\frac{21}{10}-\frac{3}{5}\right)x=60$$

10 va 5 ning eng kichik umumiy karralisi 10 ga teng. \frac{21}{10} va \frac{3}{5} ni 10 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{21}{10}-\frac{6}{10}\right)x=60$$

\frac{21}{10} va \frac{6}{10} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{21-6}{10}x=60$$

15 olish uchun 21 dan 6 ni ayirish.

$$\frac{15}{10}x=60$$

\frac{15}{10} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{3}{2}x=60$$

Ikki tarafini \frac{2}{3} va teskari kasri \frac{3}{2} ga ko‘paytiring.

$$x=60\times \frac{2}{3}$$

60\times \frac{2}{3} ni yagona kasrga aylantiring.

$$x=\frac{60\times 2}{3}$$

120 hosil qilish uchun 60 va 2 ni ko'paytirish.

$$x=\frac{120}{3}$$

40 ni olish uchun 120 ni 3 ga bo‘ling.

$$x=40$$
