3\left(4-z\right)-\left(x-3\right)=2\left(2x-3\right)
Tenglamaning ikkala tarafini 6 ga, 2,6,3 ning eng kichik karralisiga ko‘paytiring.
12-3z-\left(x-3\right)=2\left(2x-3\right)
3 ga 4-z ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
12-3z-x+3=2\left(2x-3\right)
x-3 teskarisini topish uchun har birining teskarisini toping.
15-3z-x=2\left(2x-3\right)
15 olish uchun 12 va 3'ni qo'shing.
15-3z-x=4x-6
2 ga 2x-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15-3z-x-4x=-6
Ikkala tarafdan 4x ni ayirish.
15-3z-5x=-6
-5x ni olish uchun -x va -4x ni birlashtirish.
-3z-5x=-6-15
Ikkala tarafdan 15 ni ayirish.
-3z-5x=-21
-21 olish uchun -6 dan 15 ni ayirish.
-5x=-21+3z
3z ni ikki tarafga qo’shing.
-5x=3z-21
Tenglama standart shaklda.
\frac{-5x}{-5}=\frac{3z-21}{-5}
Ikki tarafini -5 ga bo‘ling.
x=\frac{3z-21}{-5}
-5 ga bo'lish -5 ga ko'paytirishni bekor qiladi.
x=\frac{21-3z}{5}
-21+3z ni -5 ga bo'lish.
3\left(4-z\right)-\left(x-3\right)=2\left(2x-3\right)

15-3z-x=2\left(2x-3\right)
15 olish uchun 12 va 3'ni qo'shing.
15-3z-x=4x-6
2 ga 2x-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-3z-x=4x-6-15
Ikkala tarafdan 15 ni ayirish.
-3z-x=4x-21
-21 olish uchun -6 dan 15 ni ayirish.
-3z=4x-21+x
x ni ikki tarafga qo’shing.
-3z=5x-21
5x ni olish uchun 4x va x ni birlashtirish.
\frac{-3z}{-3}=\frac{5x-21}{-3}
Ikki tarafini -3 ga bo‘ling.
z=\frac{5x-21}{-3}
-3 ga bo'lish -3 ga ko'paytirishni bekor qiladi.
z=-\frac{5x}{3}+7
5x-21 ni -3 ga bo'lish.
