5/x+3/4=-4/x eching

$$\frac { 5 } { x } + \frac { 3 } { 4 } = \frac { - 4 } { x }$$

x uchun yechish

$$x=-12$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 4x ga, x,4 ning eng kichik karralisiga ko‘paytiring.

$$4\times 5+4x\times \frac{3}{4}=4\left(-4\right)$$

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

$$20+4x\times \frac{3}{4}=4\left(-4\right)$$

4 va 4 ni qisqartiring.

$$20+3x=4\left(-4\right)$$

-16 hosil qilish uchun 4 va -4 ni ko'paytirish.

$$20+3x=-16$$

Ikkala tarafdan 20 ni ayirish.

$$3x=-16-20$$

-36 olish uchun -16 dan 20 ni ayirish.

$$3x=-36$$

Ikki tarafini 3 ga bo‘ling.

$$x=\frac{-36}{3}$$

-12 ni olish uchun -36 ni 3 ga bo‘ling.

$$x=-12$$
