2/3x+1/2=-3/8 eching

$$\frac { 2 } { 3 } x + \frac { 1 } { 2 } = - \frac { 3 } { 8 }$$

x uchun yechish

$$x = -\frac{21}{16} = -1\frac{5}{16} = -1,3125$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \frac{1}{2} ni ayirish.

$$\frac{2}{3}x=-\frac{3}{8}-\frac{1}{2}$$

8 va 2 ning eng kichik umumiy karralisi 8 ga teng. -\frac{3}{8} va \frac{1}{2} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2}{3}x=-\frac{3}{8}-\frac{4}{8}$$

-\frac{3}{8} va \frac{4}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{2}{3}x=\frac{-3-4}{8}$$

-7 olish uchun -3 dan 4 ni ayirish.

$$\frac{2}{3}x=-\frac{7}{8}$$

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

$$x=-\frac{7}{8}\times \frac{3}{2}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{7}{8} ni \frac{3}{2} ga ko‘paytiring.

$$x=\frac{-7\times 3}{8\times 2}$$

\frac{-7\times 3}{8\times 2} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{-21}{16}$$

\frac{-21}{16} kasri manfiy belgini olib tashlash bilan -\frac{21}{16} sifatida qayta yozilishi mumkin.

$$x=-\frac{21}{16}$$
