10/1frac{2{5}}=35/x eching

$$\frac { 10 } { 1 \frac { 2 } { 5 } } = \frac { 35 } { x }$$

x uchun yechish

$$x = \frac{49}{10} = 4\frac{9}{10} = 4,9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x ga ko'paytirish.

$$\frac{5}{7}x\times 10=35$$

\frac{5}{7}\times 10 ni yagona kasrga aylantiring.

$$\frac{5\times 10}{7}x=35$$

50 hosil qilish uchun 5 va 10 ni ko'paytirish.

$$\frac{50}{7}x=35$$

Ikki tarafini \frac{7}{50} va teskari kasri \frac{50}{7} ga ko‘paytiring.

$$x=35\times \frac{7}{50}$$

35\times \frac{7}{50} ni yagona kasrga aylantiring.

$$x=\frac{35\times 7}{50}$$

245 hosil qilish uchun 35 va 7 ni ko'paytirish.

$$x=\frac{245}{50}$$

\frac{245}{50} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{49}{10}$$
