5-n-2/25=-15/25 eching

$$5 - n - \frac { 2 } { 25 } = - \frac { 15 } { 25 }$$

n uchun yechish

$$n = \frac{138}{25} = 5\frac{13}{25} = 5,52$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

5 ni \frac{125}{25} kasrga o‘giring.

$$\frac{125}{25}-n-\frac{2}{25}=-\frac{15}{25}$$

\frac{125}{25} va \frac{2}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{125-2}{25}-n=-\frac{15}{25}$$

123 olish uchun 125 dan 2 ni ayirish.

$$\frac{123}{25}-n=-\frac{15}{25}$$

\frac{15}{25} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{123}{25}-n=-\frac{3}{5}$$

Ikkala tarafdan \frac{123}{25} ni ayirish.

$$-n=-\frac{3}{5}-\frac{123}{25}$$

5 va 25 ning eng kichik umumiy karralisi 25 ga teng. -\frac{3}{5} va \frac{123}{25} ni 25 maxraj bilan kasrlarga aylantirib oling.

$$-n=-\frac{15}{25}-\frac{123}{25}$$

-\frac{15}{25} va \frac{123}{25} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-n=\frac{-15-123}{25}$$

-138 olish uchun -15 dan 123 ni ayirish.

$$-n=-\frac{138}{25}$$

Ikkala tarafini -1 ga ko‘paytiring.

$$n=\frac{138}{25}$$
