3/10x-2/5=2 eching

$$\frac { 3 } { 10 } x - \frac { 2 } { 5 } = 2$$

x uchun yechish

$$x=8$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{2}{5} ni ikki tarafga qo’shing.

$$\frac{3}{10}x=2+\frac{2}{5}$$

2 ni \frac{10}{5} kasrga o‘giring.

$$\frac{3}{10}x=\frac{10}{5}+\frac{2}{5}$$

\frac{10}{5} va \frac{2}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{3}{10}x=\frac{10+2}{5}$$

12 olish uchun 10 va 2'ni qo'shing.

$$\frac{3}{10}x=\frac{12}{5}$$

Ikki tarafini \frac{10}{3} va teskari kasri \frac{3}{10} ga ko‘paytiring.

$$x=\frac{12}{5}\times \frac{10}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{12}{5} ni \frac{10}{3} ga ko‘paytiring.

$$x=\frac{12\times 10}{5\times 3}$$

\frac{12\times 10}{5\times 3} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{120}{15}$$

8 ni olish uchun 120 ni 15 ga bo‘ling.

$$x=8$$
