9/2+5/2y=2y-3 eching

$$\frac { 9 } { 2 } + \frac { 5 } { 2 } y = 2 y - 3$$

y uchun yechish

$$y=-15$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2y ni ayirish.

$$\frac{9}{2}+\frac{5}{2}y-2y=-3$$

\frac{1}{2}y ni olish uchun \frac{5}{2}y va -2y ni birlashtirish.

$$\frac{9}{2}+\frac{1}{2}y=-3$$

Ikkala tarafdan \frac{9}{2} ni ayirish.

$$\frac{1}{2}y=-3-\frac{9}{2}$$

-3 ni -\frac{6}{2} kasrga o‘giring.

$$\frac{1}{2}y=-\frac{6}{2}-\frac{9}{2}$$

-\frac{6}{2} va \frac{9}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{1}{2}y=\frac{-6-9}{2}$$

-15 olish uchun -6 dan 9 ni ayirish.

$$\frac{1}{2}y=-\frac{15}{2}$$

Ikki tarafini 2 va teskari kasri \frac{1}{2} ga ko‘paytiring.

$$y=-\frac{15}{2}\times 2$$

2 va 2 ni qisqartiring.

$$y=-15$$
