12*[7+(+15)-8]=[3x-18]+[2*(10)]+12 eching

$$12 \times [ 7 + ( + 15 ) - 8 ] = [ 3 x - 18 ] + [ 2 \times ( 10 ) ] + 12$$

x uchun yechish

$$x = \frac{154}{3} = 51\frac{1}{3} \approx 51,333333333$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

22 olish uchun 7 va 15'ni qo'shing.

$$12\left(22-8\right)=3x-18+2\times 10+12$$

14 olish uchun 22 dan 8 ni ayirish.

$$12\times 14=3x-18+2\times 10+12$$

168 hosil qilish uchun 12 va 14 ni ko'paytirish.

$$168=3x-18+2\times 10+12$$

20 hosil qilish uchun 2 va 10 ni ko'paytirish.

$$168=3x-18+20+12$$

2 olish uchun -18 va 20'ni qo'shing.

$$168=3x+2+12$$

14 olish uchun 2 va 12'ni qo'shing.

$$168=3x+14$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$3x+14=168$$

Ikkala tarafdan 14 ni ayirish.

$$3x=168-14$$

154 olish uchun 168 dan 14 ni ayirish.

$$3x=154$$

Ikki tarafini 3 ga bo‘ling.

$$x=\frac{154}{3}$$
