x=2x-10/20 eching

$$x = \frac { 2 x - 10 } { 20 }$$

x uchun yechish

$$x=-\frac{5}{9}\approx -0,555555556$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{1}{10}x-\frac{1}{2} natijani olish uchun 2x-10 ning har bir ifodasini 20 ga bo‘ling.

$$x=\frac{1}{10}x-\frac{1}{2}$$

Ikkala tarafdan \frac{1}{10}x ni ayirish.

$$x-\frac{1}{10}x=-\frac{1}{2}$$

\frac{9}{10}x ni olish uchun x va -\frac{1}{10}x ni birlashtirish.

$$\frac{9}{10}x=-\frac{1}{2}$$

Ikki tarafini \frac{10}{9} va teskari kasri \frac{9}{10} ga ko‘paytiring.

$$x=-\frac{1}{2}\times \frac{10}{9}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{1}{2} ni \frac{10}{9} ga ko‘paytiring.

$$x=\frac{-10}{2\times 9}$$

\frac{-10}{2\times 9} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{-10}{18}$$

\frac{-10}{18} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=-\frac{5}{9}$$
