dx+b=7x-7d
7 ga x-d ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
dx+b+7d=7x
7d ni ikki tarafga qo’shing.
dx+7d=7x-b
Ikkala tarafdan b ni ayirish.
\left(x+7\right)d=7x-b
d'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(x+7\right)d}{x+7}=\frac{7x-b}{x+7}
Ikki tarafini x+7 ga bo‘ling.
d=\frac{7x-b}{x+7}
x+7 ga bo'lish x+7 ga ko'paytirishni bekor qiladi.
