3/5y-2=7/10 eching

$$\frac { 3 } { 5 } y - 2 = \frac { 7 } { 10 }$$

y uchun yechish

$$y = \frac{9}{2} = 4\frac{1}{2} = 4,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 ni ikki tarafga qo’shing.

$$\frac{3}{5}y=\frac{7}{10}+2$$

2 ni \frac{20}{10} kasrga o‘giring.

$$\frac{3}{5}y=\frac{7}{10}+\frac{20}{10}$$

\frac{7}{10} va \frac{20}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3}{5}y=\frac{7+20}{10}$$

27 olish uchun 7 va 20'ni qo'shing.

$$\frac{3}{5}y=\frac{27}{10}$$

Ikki tarafini \frac{5}{3} va teskari kasri \frac{3}{5} ga ko‘paytiring.

$$y=\frac{27}{10}\times \frac{5}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{27}{10} ni \frac{5}{3} ga ko‘paytiring.

$$y=\frac{27\times 5}{10\times 3}$$

\frac{27\times 5}{10\times 3} kasridagi ko‘paytirishlarni bajaring.

$$y=\frac{135}{30}$$

\frac{135}{30} ulushini 15 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$y=\frac{9}{2}$$
