-1/5y+1/3=-1/4 eching

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

y uchun yechish

$$y = \frac{35}{12} = 2\frac{11}{12} \approx 2,916666667$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \frac{1}{3} ni ayirish.

$$-\frac{1}{5}y=-\frac{1}{4}-\frac{1}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. -\frac{1}{4} va \frac{1}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{5}y=-\frac{3}{12}-\frac{4}{12}$$

-\frac{3}{12} va \frac{4}{12} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-\frac{1}{5}y=\frac{-3-4}{12}$$

-7 olish uchun -3 dan 4 ni ayirish.

$$-\frac{1}{5}y=-\frac{7}{12}$$

Ikki tarafini -5 va teskari kasri -\frac{1}{5} ga ko‘paytiring.

$$y=-\frac{7}{12}\left(-5\right)$$

-\frac{7}{12}\left(-5\right) ni yagona kasrga aylantiring.

$$y=\frac{-7\left(-5\right)}{12}$$

35 hosil qilish uchun -7 va -5 ni ko'paytirish.

$$y=\frac{35}{12}$$
