Klipbordga nusxa olish
13\left(2x-10\right)+20\left(4x+5\right)=1560
Tenglamaning ikkala tarafini 260 ga, 20,13 ning eng kichik karralisiga ko‘paytiring.
26x-130+20\left(4x+5\right)=1560
13 ga 2x-10 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
26x-130+80x+100=1560
20 ga 4x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
106x-130+100=1560
106x ni olish uchun 26x va 80x ni birlashtirish.
106x-30=1560
-30 olish uchun -130 va 100'ni qo'shing.
106x=1560+30
30 ni ikki tarafga qo’shing.
106x=1590
1590 olish uchun 1560 va 30'ni qo'shing.
x=\frac{1590}{106}
Ikki tarafini 106 ga bo‘ling.
x=15
15 ni olish uchun 1590 ni 106 ga bo‘ling.
