$$3 \frac { 2 } { 5 } y + 1 \frac { 1 } { 4 } = 7 \frac { 1 } { 3 }$$

y uchun yechish

$$y = \frac{365}{204} = 1\frac{161}{204} \approx 1,789215686$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 60 ga, 5,4,3 ning eng kichik karralisiga ko‘paytiring.

$$12\left(3\times 5+2\right)y+15\left(1\times 4+1\right)=20\left(7\times 3+1\right)$$

15 hosil qilish uchun 3 va 5 ni ko'paytirish.

$$12\left(15+2\right)y+15\left(1\times 4+1\right)=20\left(7\times 3+1\right)$$

17 olish uchun 15 va 2'ni qo'shing.

$$12\times 17y+15\left(1\times 4+1\right)=20\left(7\times 3+1\right)$$

204 hosil qilish uchun 12 va 17 ni ko'paytirish.

$$204y+15\left(1\times 4+1\right)=20\left(7\times 3+1\right)$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$204y+15\left(4+1\right)=20\left(7\times 3+1\right)$$

5 olish uchun 4 va 1'ni qo'shing.

$$204y+15\times 5=20\left(7\times 3+1\right)$$

75 hosil qilish uchun 15 va 5 ni ko'paytirish.

$$204y+75=20\left(7\times 3+1\right)$$

21 hosil qilish uchun 7 va 3 ni ko'paytirish.

$$204y+75=20\left(21+1\right)$$

22 olish uchun 21 va 1'ni qo'shing.

$$204y+75=20\times 22$$

440 hosil qilish uchun 20 va 22 ni ko'paytirish.

$$204y+75=440$$

Ikkala tarafdan 75 ni ayirish.

$$204y=440-75$$

365 olish uchun 440 dan 75 ni ayirish.

$$204y=365$$

Ikki tarafini 204 ga bo‘ling.

$$y=\frac{365}{204}$$
