4/5+x=6/8 eching

$$\frac { 4 } { 5 } + x = \frac { 6 } { 8 }$$

x uchun yechish

$$x=-\frac{1}{20}=-0,05$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

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

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

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

4 va 5 ning eng kichik umumiy karralisi 20 ga teng. \frac{3}{4} va \frac{4}{5} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$x=\frac{15}{20}-\frac{16}{20}$$

\frac{15}{20} va \frac{16}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x=\frac{15-16}{20}$$

-1 olish uchun 15 dan 16 ni ayirish.

$$x=-\frac{1}{20}$$
