2-7z=13/3 eching

$$2 - 7 z = \frac { 13 } { 3 }$$

z uchun yechish

$$z=-\frac{1}{3}\approx -0,333333333$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2 ni ayirish.

$$-7z=\frac{13}{3}-2$$

2 ni \frac{6}{3} kasrga o‘giring.

$$-7z=\frac{13}{3}-\frac{6}{3}$$

\frac{13}{3} va \frac{6}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-7z=\frac{13-6}{3}$$

7 olish uchun 13 dan 6 ni ayirish.

$$-7z=\frac{7}{3}$$

Ikki tarafini -7 ga bo‘ling.

$$z=\frac{\frac{7}{3}}{-7}$$

\frac{\frac{7}{3}}{-7} ni yagona kasrga aylantiring.

$$z=\frac{7}{3\left(-7\right)}$$

-21 hosil qilish uchun 3 va -7 ni ko'paytirish.

$$z=\frac{7}{-21}$$

\frac{7}{-21} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$z=-\frac{1}{3}$$
