-14k+98+7=56
-14 ga k-7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-14k+105=56
105 olish uchun 98 va 7'ni qo'shing.
-14k=56-105
Ikkala tarafdan 105 ni ayirish.
-14k=-49
-49 olish uchun 56 dan 105 ni ayirish.
k=\frac{-49}{-14}
Ikki tarafini -14 ga bo‘ling.
k=\frac{7}{2}
\frac{-49}{-14} ulushini -7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
