1/4+x=2/10 eching

$$\frac { 1 } { 4 } + x = \frac { 2 } { 10 }$$

x uchun yechish

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

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{2}{10} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{4}+x=\frac{1}{5}$$

Ikkala tarafdan \frac{1}{4} ni ayirish.

$$x=\frac{1}{5}-\frac{1}{4}$$

5 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{1}{5} va \frac{1}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$x=\frac{4}{20}-\frac{5}{20}$$

\frac{4}{20} va \frac{5}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x=\frac{4-5}{20}$$

-1 olish uchun 4 dan 5 ni ayirish.

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