Chiziqli tenglamalarni yechish bo'yicha qadamlar

Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$21+11x=13x$$

Ikkala tarafdan 13x ni ayirish.

$$21+11x-13x=0$$

-2x ni olish uchun 11x va -13x ni birlashtirish.

$$21-2x=0$$

Ikkala tarafdan 21 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-2x=-21$$

Ikki tarafini -2 ga bo‘ling.

$$x=\frac{-21}{-2}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-21}{-2} kasrini \frac{21}{2} ga soddalashtirish mumkin.

$$x=\frac{21}{2}$$
