877=(x*56)+(x*87)+(81-2x*88) eching

$$877 = ( x \times 56 ) + ( x \times 87 ) + ( 81 - 2 x \times 88 )$$

x uchun yechish

$$x = -\frac{796}{33} = -24\frac{4}{33} \approx -24,121212121$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

143x ni olish uchun x\times 56 va x\times 87 ni birlashtirish.

$$877=143x+81-2x\times 88$$

176 hosil qilish uchun 2 va 88 ni ko'paytirish.

$$877=143x+81-176x$$

-33x ni olish uchun 143x va -176x ni birlashtirish.

$$877=-33x+81$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-33x+81=877$$

Ikkala tarafdan 81 ni ayirish.

$$-33x=877-81$$

796 olish uchun 877 dan 81 ni ayirish.

$$-33x=796$$

Ikki tarafini -33 ga bo‘ling.

$$x=\frac{796}{-33}$$

\frac{796}{-33} kasri manfiy belgini olib tashlash bilan -\frac{796}{33} sifatida qayta yozilishi mumkin.

$$x=-\frac{796}{33}$$
