-2*4-t*3=-15*(2*4)+42 eching

$$- 2 \cdot 4 - t \cdot 3 = - 15 \times ( 2 \cdot 4 ) + 42$$

t uchun yechish

$$t = \frac{70}{3} = 23\frac{1}{3} \approx 23,333333333$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-8 hosil qilish uchun -2 va 4 ni ko'paytirish.

$$-8-t\times 3=-15\times 2\times 4+42$$

-30 hosil qilish uchun -15 va 2 ni ko'paytirish.

$$-8-t\times 3=-30\times 4+42$$

-120 hosil qilish uchun -30 va 4 ni ko'paytirish.

$$-8-t\times 3=-120+42$$

-78 olish uchun -120 va 42'ni qo'shing.

$$-8-t\times 3=-78$$

-3 hosil qilish uchun -1 va 3 ni ko'paytirish.

$$-8-3t=-78$$

8 ni ikki tarafga qo’shing.

$$-3t=-78+8$$

-70 olish uchun -78 va 8'ni qo'shing.

$$-3t=-70$$

Ikki tarafini -3 ga bo‘ling.

$$t=\frac{-70}{-3}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-70}{-3} kasrini \frac{70}{3} ga soddalashtirish mumkin.

$$t=\frac{70}{3}$$
