x+56=3\left(16+x\right)
x qiymati -56 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 3\left(x+56\right) ga, 3,56+x ning eng kichik karralisiga ko‘paytiring.
x+56=48+3x
3 ga 16+x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x+56-3x=48
Ikkala tarafdan 3x ni ayirish.
-2x+56=48
-2x ni olish uchun x va -3x ni birlashtirish.
-2x=48-56
Ikkala tarafdan 56 ni ayirish.
-2x=-8
-8 olish uchun 48 dan 56 ni ayirish.
x=\frac{-8}{-2}
Ikki tarafini -2 ga bo‘ling.
x=4
4 ni olish uchun -8 ni -2 ga bo‘ling.
