c=4-d/d+3 eching

$$c = \frac { 4 - d } { d + 3 }$$

d uchun yechish

$$d=-\frac{3c-4}{c+1}$$

$$c\neq -1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

d qiymati -3 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini d+3 ga ko'paytirish.

$$c\left(d+3\right)=4-d$$

c ga d+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$cd+3c=4-d$$

d ni ikki tarafga qo’shing.

$$cd+3c+d=4$$

Ikkala tarafdan 3c ni ayirish.

$$cd+d=4-3c$$

d'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(c+1\right)d=4-3c$$

Ikki tarafini c+1 ga bo‘ling.

$$\frac{\left(c+1\right)d}{c+1}=\frac{4-3c}{c+1}$$

c+1 ga bo'lish c+1 ga ko'paytirishni bekor qiladi.

$$d=\frac{4-3c}{c+1}$$

d qiymati -3 teng bo‘lmaydi.

$$d=\frac{4-3c}{c+1}\text{, }d\neq -3$$

c uchun yechish

$$c=-\frac{d-4}{d+3}$$

$$d\neq -3$$
