$$a 6 x - 13 y = - 22 \text { to find } y \text { if } x = 11$$

x, y uchun yechish

$$x=11$$

$$y=\frac{11\left(a_{6}+2\right)}{13}$$

O'rnini bosishdan foydalanish qoidalari

Almashtirishdan foydalanib tenglamalar juftligini yechish uchun, avval o'zgaruvchan qiymatlardan biri uchun tenglamani yeching. So'ngra ana shu o'zgaruvchan natijani boshqa tenglama bilan almashtiring.

$$x=11,a_{6}x-13y=-22$$

Teng belgisining chap tarafida x ni x bilan yechish uchun qulayroq bo'lgan ikki tenglamaning birini tanlang.

$$x=11$$

11 ni x uchun boshqa tenglamada almashtirish, a_{6}x-13y=-22.

$$a_{6}\times 11-13y=-22$$

a_{6} ni 11 marotabaga ko'paytirish.

$$11a_{6}-13y=-22$$

Tenglamaning ikkala tarafidan 11a_{6} ni ayirish.

$$-13y=-11a_{6}-22$$

Ikki tarafini -13 ga bo‘ling.

$$y=\frac{11a_{6}+22}{13}$$

Tizim hal qilindi.

$$x=11,y=\frac{11a_{6}+22}{13}$$
