-5=-4/5(8)+b eching

$$- 5 = - \frac { 4 } { 5 } ( 8 ) + b$$

b uchun yechish

$$b = \frac{7}{5} = 1\frac{2}{5} = 1,4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-\frac{4}{5}\times 8 ni yagona kasrga aylantiring.

$$-5=\frac{-4\times 8}{5}+b$$

-32 hosil qilish uchun -4 va 8 ni ko'paytirish.

$$-5=\frac{-32}{5}+b$$

\frac{-32}{5} kasri manfiy belgini olib tashlash bilan -\frac{32}{5} sifatida qayta yozilishi mumkin.

$$-5=-\frac{32}{5}+b$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-\frac{32}{5}+b=-5$$

\frac{32}{5} ni ikki tarafga qo’shing.

$$b=-5+\frac{32}{5}$$

-5 ni -\frac{25}{5} kasrga o‘giring.

$$b=-\frac{25}{5}+\frac{32}{5}$$

-\frac{25}{5} va \frac{32}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$b=\frac{-25+32}{5}$$

7 olish uchun -25 va 32'ni qo'shing.

$$b=\frac{7}{5}$$
