9r-1/2=5/6 eching

$$9 r - \frac { 1 } { 2 } = \frac { 5 } { 6 }$$

r uchun yechish

$$r=\frac{4}{27}\approx 0,148148148$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{1}{2} ni ikki tarafga qo’shing.

$$9r=\frac{5}{6}+\frac{1}{2}$$

6 va 2 ning eng kichik umumiy karralisi 6 ga teng. \frac{5}{6} va \frac{1}{2} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$9r=\frac{5}{6}+\frac{3}{6}$$

\frac{5}{6} va \frac{3}{6} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$9r=\frac{5+3}{6}$$

8 olish uchun 5 va 3'ni qo'shing.

$$9r=\frac{8}{6}$$

\frac{8}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$9r=\frac{4}{3}$$

Ikki tarafini 9 ga bo‘ling.

$$r=\frac{\frac{4}{3}}{9}$$

\frac{\frac{4}{3}}{9} ni yagona kasrga aylantiring.

$$r=\frac{4}{3\times 9}$$

27 hosil qilish uchun 3 va 9 ni ko'paytirish.

$$r=\frac{4}{27}$$
