7000\left(x-3\right)=20000
x qiymati 3 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x-3 ga ko'paytirish.
7000x-21000=20000
7000 ga x-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
7000x=20000+21000
21000 ni ikki tarafga qo’shing.
7000x=41000
41000 olish uchun 20000 va 21000'ni qo'shing.
x=\frac{41000}{7000}
Ikki tarafini 7000 ga bo‘ling.
x=\frac{41}{7}
\frac{41000}{7000} ulushini 1000 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
