(2/3x+1)+1/4=12 eching

$$( \frac { 2 } { 3 } x + 1 ) + \frac { 1 } { 4 } = 12$$

x uchun yechish

$$x = \frac{129}{8} = 16\frac{1}{8} = 16,125$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

1 ni \frac{4}{4} kasrga o‘giring.

$$\frac{2}{3}x+\frac{4}{4}+\frac{1}{4}=12$$

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

$$\frac{2}{3}x+\frac{4+1}{4}=12$$

5 olish uchun 4 va 1'ni qo'shing.

$$\frac{2}{3}x+\frac{5}{4}=12$$

Ikkala tarafdan \frac{5}{4} ni ayirish.

$$\frac{2}{3}x=12-\frac{5}{4}$$

12 ni \frac{48}{4} kasrga o‘giring.

$$\frac{2}{3}x=\frac{48}{4}-\frac{5}{4}$$

\frac{48}{4} va \frac{5}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{2}{3}x=\frac{48-5}{4}$$

43 olish uchun 48 dan 5 ni ayirish.

$$\frac{2}{3}x=\frac{43}{4}$$

Ikki tarafini \frac{3}{2} va teskari kasri \frac{2}{3} ga ko‘paytiring.

$$x=\frac{43}{4}\times \frac{3}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{43}{4} ni \frac{3}{2} ga ko‘paytiring.

$$x=\frac{43\times 3}{4\times 2}$$

\frac{43\times 3}{4\times 2} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{129}{8}$$
