m/1-m-1/2+m-2/3=1 eching

$$\frac { m } { 1 } - \frac { m - 1 } { 2 } + \frac { m - 2 } { 3 } = 1$$

m uchun yechish

$$m = \frac{7}{5} = 1\frac{2}{5} = 1,4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 6 ga, 2,3 ning eng kichik karralisiga ko‘paytiring.

$$6m-3\left(m-1\right)+2\left(m-2\right)=6$$

-3 ga m-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6m-3m+3+2\left(m-2\right)=6$$

3m ni olish uchun 6m va -3m ni birlashtirish.

$$3m+3+2\left(m-2\right)=6$$

2 ga m-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3m+3+2m-4=6$$

5m ni olish uchun 3m va 2m ni birlashtirish.

$$5m+3-4=6$$

-1 olish uchun 3 dan 4 ni ayirish.

$$5m-1=6$$

1 ni ikki tarafga qo’shing.

$$5m=6+1$$

7 olish uchun 6 va 1'ni qo'shing.

$$5m=7$$

Ikki tarafini 5 ga bo‘ling.

$$m=\frac{7}{5}$$
