-p(d+z)=-2z+59 eching

$$- p ( d + z ) = - 2 z + 59$$

d uchun yechish

$$\left\{\begin{matrix}d=-\frac{pz-2z+59}{p}\text{, }&p\neq 0\\d\in \mathrm{R}\text{, }&z=\frac{59}{2}\text{ and }p=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-p ga d+z ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$\left(-p\right)d+\left(-p\right)z=-2z+59$$

Ikkala tarafdan \left(-p\right)z ni ayirish.

$$\left(-p\right)d=-2z+59-\left(-p\right)z$$

1 hosil qilish uchun -1 va -1 ni ko'paytirish.

$$-pd=-2z+59+pz$$

Tenglama standart shaklda.

$$\left(-p\right)d=pz-2z+59$$

Ikki tarafini -p ga bo‘ling.

$$\frac{\left(-p\right)d}{-p}=\frac{pz-2z+59}{-p}$$

-p ga bo'lish -p ga ko'paytirishni bekor qiladi.

$$d=\frac{pz-2z+59}{-p}$$

zp-2z+59 ni -p ga bo'lish.

$$d=-\frac{pz-2z+59}{p}$$

p uchun yechish

$$\left\{\begin{matrix}p=\frac{2z-59}{z+d}\text{, }&d\neq -z\\p\in \mathrm{R}\text{, }&z=\frac{59}{2}\text{ and }d=-\frac{59}{2}\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-p ga d+z ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$\left(-p\right)d+\left(-p\right)z=-2z+59$$

Shartlarni qayta saralash.

$$-pz-dp=-2z+59$$

p'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(-z-d\right)p=-2z+59$$

Tenglama standart shaklda.

$$\left(-z-d\right)p=59-2z$$

Ikki tarafini -z-d ga bo‘ling.

$$\frac{\left(-z-d\right)p}{-z-d}=\frac{59-2z}{-z-d}$$

-z-d ga bo'lish -z-d ga ko'paytirishni bekor qiladi.

$$p=\frac{59-2z}{-z-d}$$

-2z+59 ni -z-d ga bo'lish.

$$p=-\frac{59-2z}{z+d}$$
