-x-\left(-12\right)=-4\left(3x+5\right)
x-12 teskarisini topish uchun har birining teskarisini toping.
-x+12=-4\left(3x+5\right)
-12 ning teskarisi 12 ga teng.
-x+12=-12x-20
-4 ga 3x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-x+12+12x=-20
12x ni ikki tarafga qo’shing.
11x+12=-20
11x ni olish uchun -x va 12x ni birlashtirish.
11x=-20-12
