$$5 \cdot 4 \ell - \frac { 1 } { 2 } \ell - 766 m \ell = \quad m \ell$$

m uchun yechish

$$\left\{\begin{matrix}\\m=\frac{3}{118}\approx 0,025423729\text{, }&\text{unconditionally}\\m\in \mathrm{R}\text{, }&ℓ=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$20ℓ-\frac{1}{2}ℓ-766mℓ=mℓ$$

\frac{39}{2}ℓ ni olish uchun 20ℓ va -\frac{1}{2}ℓ ni birlashtirish.

$$\frac{39}{2}ℓ-766mℓ=mℓ$$

Ikkala tarafdan mℓ ni ayirish.

$$\frac{39}{2}ℓ-766mℓ-mℓ=0$$

-767mℓ ni olish uchun -766mℓ va -mℓ ni birlashtirish.

$$\frac{39}{2}ℓ-767mℓ=0$$

Ikkala tarafdan \frac{39}{2}ℓ ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-767mℓ=-\frac{39}{2}ℓ$$

Tenglama standart shaklda.

$$\left(-767ℓ\right)m=-\frac{39ℓ}{2}$$

Ikki tarafini -767ℓ ga bo‘ling.

$$\frac{\left(-767ℓ\right)m}{-767ℓ}=-\frac{\frac{39ℓ}{2}}{-767ℓ}$$

-767ℓ ga bo'lish -767ℓ ga ko'paytirishni bekor qiladi.

$$m=-\frac{\frac{39ℓ}{2}}{-767ℓ}$$

-\frac{39ℓ}{2} ni -767ℓ ga bo'lish.

$$m=\frac{3}{118}$$

$$\frac{39}{2}ℓ-766mℓ-mℓ=0$$

-767mℓ ni olish uchun -766mℓ va -mℓ ni birlashtirish.

$$\frac{39}{2}ℓ-767mℓ=0$$

ℓ'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(\frac{39}{2}-767m\right)ℓ=0$$

0 ni \frac{39}{2}-767m ga bo'lish.

$$ℓ=0$$
