-55=5left(2{a}_{1}(9)-3right) eching

$$-55 = 5 \left( 2 { a }_{ 1 } (9)-3 \right)$$

a_1 uchun yechish

$$a_{1}=-\frac{4}{9}\approx -0,444444444$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 5 ga bo‘ling.

$$\frac{-55}{5}=2a_{1}\times 9-3$$

-11 ni olish uchun -55 ni 5 ga bo‘ling.

$$-11=2a_{1}\times 9-3$$

18 hosil qilish uchun 2 va 9 ni ko'paytirish.

$$-11=18a_{1}-3$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$18a_{1}-3=-11$$

3 ni ikki tarafga qo’shing.

$$18a_{1}=-11+3$$

-8 olish uchun -11 va 3'ni qo'shing.

$$18a_{1}=-8$$

Ikki tarafini 18 ga bo‘ling.

$$a_{1}=\frac{-8}{18}$$

\frac{-8}{18} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$a_{1}=-\frac{4}{9}$$
