4\left(x+17\right)=40-5\left(2x-7\right)
Tenglamaning ikkala tarafini 20 ga, 5,4 ning eng kichik karralisiga ko‘paytiring.
4x+68=40-5\left(2x-7\right)
4 ga x+17 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x+68=40-10x+35
-5 ga 2x-7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x+68=75-10x
75 olish uchun 40 va 35'ni qo'shing.
4x+68+10x=75
10x ni ikki tarafga qo’shing.
14x+68=75
14x ni olish uchun 4x va 10x ni birlashtirish.
14x=75-68
Ikkala tarafdan 68 ni ayirish.
14x=7
7 olish uchun 75 dan 68 ni ayirish.
x=\frac{7}{14}
Ikki tarafini 14 ga bo‘ling.
x=\frac{1}{2}
\frac{7}{14} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
