2*1x-6*45=3*15-4*3x eching

$$2 \cdot 1 x - 6 \cdot 45 = 3 \cdot 15 - 4 \cdot 3 x$$

x uchun yechish

$$x = \frac{45}{2} = 22\frac{1}{2} = 22,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 hosil qilish uchun 2 va 1 ni ko'paytirish.

$$2x-6\times 45=3\times 15-4\times 3x$$

270 hosil qilish uchun 6 va 45 ni ko'paytirish.

$$2x-270=3\times 15-4\times 3x$$

45 hosil qilish uchun 3 va 15 ni ko'paytirish.

$$2x-270=45-4\times 3x$$

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$2x-270=45-12x$$

12x ni ikki tarafga qo’shing.

$$2x-270+12x=45$$

14x ni olish uchun 2x va 12x ni birlashtirish.

$$14x-270=45$$

270 ni ikki tarafga qo’shing.

$$14x=45+270$$

315 olish uchun 45 va 270'ni qo'shing.

$$14x=315$$

Ikki tarafini 14 ga bo‘ling.

$$x=\frac{315}{14}$$

\frac{315}{14} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{45}{2}$$
