3\left(-2+k\right)=5\left(2-\left(-2\right)\right)
Tenglamaning ikkala tarafini 15 ga, 5,3 ning eng kichik karralisiga ko‘paytiring.
-6+3k=5\left(2-\left(-2\right)\right)
3 ga -2+k ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-6+3k=5\left(2+2\right)
-2 ning teskarisi 2 ga teng.
-6+3k=5\times 4
4 olish uchun 2 va 2'ni qo'shing.

20 hosil qilish uchun 5 va 4 ni ko'paytirish.
3k=20+6
6 ni ikki tarafga qo’shing.
3k=26
26 olish uchun 20 va 6'ni qo'shing.
k=\frac{26}{3}
Ikki tarafini 3 ga bo‘ling.
