x+2/3-1/2=17/18 eching

$$x + \frac { 2 } { 3 } - \frac { 1 } { 2 } = \frac { 17 } { 18 }$$

x uchun yechish

$$x=\frac{7}{9}\approx 0,777777778$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{2}{3} va \frac{1}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$x+\frac{4}{6}-\frac{3}{6}=\frac{17}{18}$$

\frac{4}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x+\frac{4-3}{6}=\frac{17}{18}$$

1 olish uchun 4 dan 3 ni ayirish.

$$x+\frac{1}{6}=\frac{17}{18}$$

Ikkala tarafdan \frac{1}{6} ni ayirish.

$$x=\frac{17}{18}-\frac{1}{6}$$

18 va 6 ning eng kichik umumiy karralisi 18 ga teng. \frac{17}{18} va \frac{1}{6} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$x=\frac{17}{18}-\frac{3}{18}$$

\frac{17}{18} va \frac{3}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x=\frac{17-3}{18}$$

14 olish uchun 17 dan 3 ni ayirish.

$$x=\frac{14}{18}$$

\frac{14}{18} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{7}{9}$$
