5*068+09x/5+x=075 eching

$$\frac{ 5 \cdot 068+09x }{ 5+x } =075$$

x uchun yechish

$$x\neq -5$$

Yechim qadamlari

x qiymati -5 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x+5 ga ko'paytirish.

$$5\times 0\times 68+0\times 9x=0\times 75\left(x+5\right)$$

Ko‘paytirishlarni bajaring.

$$0\times 68+0x=0\times 75\left(x+5\right)$$

0 hosil qilish uchun 0 va 68 ni ko'paytirish.

$$0+0x=0\times 75\left(x+5\right)$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$0+0=0\times 75\left(x+5\right)$$

0 olish uchun 0 va 0'ni qo'shing.

$$0=0\times 75\left(x+5\right)$$

0 hosil qilish uchun 0 va 75 ni ko'paytirish.

$$0=0\left(x+5\right)$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$0=0$$

0 va 0 ni taqqoslang.

$$\text{true}$$

Bu har qanday x uchun to‘g‘ri.

$$x\in \mathrm{R}$$

x qiymati -5 teng bo‘lmaydi.

$$x\in \mathrm{R}\setminus -5$$
