3+y/5=-12-4y/-2 eching

$$\frac { 3 + y } { 5 } = \frac { - 12 - 4 y } { - 2 }$$

y uchun yechish

$$y=-3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 10 ga, 5,-2 ning eng kichik karralisiga ko‘paytiring.

$$2\left(3+y\right)=-5\left(-12-4y\right)$$

2 ga 3+y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6+2y=-5\left(-12-4y\right)$$

-5 ga -12-4y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6+2y=60+20y$$

Ikkala tarafdan 20y ni ayirish.

$$6+2y-20y=60$$

-18y ni olish uchun 2y va -20y ni birlashtirish.

$$6-18y=60$$

Ikkala tarafdan 6 ni ayirish.

$$-18y=60-6$$

54 olish uchun 60 dan 6 ni ayirish.

$$-18y=54$$

Ikki tarafini -18 ga bo‘ling.

$$y=\frac{54}{-18}$$

-3 ni olish uchun 54 ni -18 ga bo‘ling.

$$y=-3$$
