1/4x+1/5=-5 eching

$$\frac { 1 } { 4 } x + \frac { 1 } { 5 } = - 5$$

x uchun yechish

$$x = -\frac{104}{5} = -20\frac{4}{5} = -20,8$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \frac{1}{5} ni ayirish.

$$\frac{1}{4}x=-5-\frac{1}{5}$$

-5 ni -\frac{25}{5} kasrga o‘giring.

$$\frac{1}{4}x=-\frac{25}{5}-\frac{1}{5}$$

-\frac{25}{5} va \frac{1}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1}{4}x=\frac{-25-1}{5}$$

-26 olish uchun -25 dan 1 ni ayirish.

$$\frac{1}{4}x=-\frac{26}{5}$$

Ikki tarafini 4 va teskari kasri \frac{1}{4} ga ko‘paytiring.

$$x=-\frac{26}{5}\times 4$$

-\frac{26}{5}\times 4 ni yagona kasrga aylantiring.

$$x=\frac{-26\times 4}{5}$$

-104 hosil qilish uchun -26 va 4 ni ko'paytirish.

$$x=\frac{-104}{5}$$

\frac{-104}{5} kasri manfiy belgini olib tashlash bilan -\frac{104}{5} sifatida qayta yozilishi mumkin.

$$x=-\frac{104}{5}$$
