3/8a-4=-1/4 eching

$$\frac { 3 } { 8 } a - 4 = - \frac { 1 } { 4 }$$

a uchun yechish

$$a=10$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

4 ni ikki tarafga qo’shing.

$$\frac{3}{8}a=-\frac{1}{4}+4$$

4 ni \frac{16}{4} kasrga o‘giring.

$$\frac{3}{8}a=-\frac{1}{4}+\frac{16}{4}$$

-\frac{1}{4} va \frac{16}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3}{8}a=\frac{-1+16}{4}$$

15 olish uchun -1 va 16'ni qo'shing.

$$\frac{3}{8}a=\frac{15}{4}$$

Ikki tarafini \frac{8}{3} va teskari kasri \frac{3}{8} ga ko‘paytiring.

$$a=\frac{15}{4}\times \frac{8}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{15}{4} ni \frac{8}{3} ga ko‘paytiring.

$$a=\frac{15\times 8}{4\times 3}$$

\frac{15\times 8}{4\times 3} kasridagi ko‘paytirishlarni bajaring.

$$a=\frac{120}{12}$$

10 ni olish uchun 120 ni 12 ga bo‘ling.

$$a=10$$
