-(-5s-5)+8(s-5)=0 eching

$$- ( - 5 s - 5 ) + 8 ( s - 5 ) = 0$$

s uchun yechish

$$s = \frac{35}{13} = 2\frac{9}{13} \approx 2,692307692$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-5s-5 teskarisini topish uchun har birining teskarisini toping.

$$-\left(-5s\right)-\left(-5\right)+8\left(s-5\right)=0$$

-5s ning teskarisi 5s ga teng.

$$5s-\left(-5\right)+8\left(s-5\right)=0$$

-5 ning teskarisi 5 ga teng.

$$5s+5+8\left(s-5\right)=0$$

8 ga s-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$5s+5+8s-40=0$$

13s ni olish uchun 5s va 8s ni birlashtirish.

$$13s+5-40=0$$

-35 olish uchun 5 dan 40 ni ayirish.

$$13s-35=0$$

35 ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$13s=35$$

Ikki tarafini 13 ga bo‘ling.

$$s=\frac{35}{13}$$
