63:x-2=-51/3*3-4 eching

$$63 : x - 2 = - 5 \frac { 1 } { 3 } \cdot 3 - 4$$

x uchun yechish

$$x = -\frac{7}{2} = -3\frac{1}{2} = -3,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 3x ga, x,3 ning eng kichik karralisiga ko‘paytiring.

$$3\times 63+3x\left(-2\right)=\left(-\frac{5\times 3+1}{3}\right)\times 3\times 3x+3x\left(-4\right)$$

189 hosil qilish uchun 3 va 63 ni ko'paytirish.

$$189+3x\left(-2\right)=\left(-\frac{5\times 3+1}{3}\right)\times 3\times 3x+3x\left(-4\right)$$

-6 hosil qilish uchun 3 va -2 ni ko'paytirish.

$$189-6x=\left(-\frac{5\times 3+1}{3}\right)\times 3\times 3x+3x\left(-4\right)$$

15 hosil qilish uchun 5 va 3 ni ko'paytirish.

$$189-6x=\left(-\frac{15+1}{3}\right)\times 3\times 3x+3x\left(-4\right)$$

16 olish uchun 15 va 1'ni qo'shing.

$$189-6x=-\frac{16}{3}\times 3\times 3x+3x\left(-4\right)$$

3 va 3 ni qisqartiring.

$$189-6x=-16\times 3x+3x\left(-4\right)$$

-48 hosil qilish uchun -16 va 3 ni ko'paytirish.

$$189-6x=-48x+3x\left(-4\right)$$

-12 hosil qilish uchun 3 va -4 ni ko'paytirish.

$$189-6x=-48x-12x$$

-60x ni olish uchun -48x va -12x ni birlashtirish.

$$189-6x=-60x$$

60x ni ikki tarafga qo’shing.

$$189-6x+60x=0$$

54x ni olish uchun -6x va 60x ni birlashtirish.

$$189+54x=0$$

Ikkala tarafdan 189 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$54x=-189$$

Ikki tarafini 54 ga bo‘ling.

$$x=\frac{-189}{54}$$

\frac{-189}{54} ulushini 27 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=-\frac{7}{2}$$
