Baham ko'rish
Klipbordga nusxa olish
x+5+2z=215-3y
Ikkala tarafdan 3y ni ayirish.
x+2z=215-3y-5
Ikkala tarafdan 5 ni ayirish.
x+2z=210-3y
210 olish uchun 215 dan 5 ni ayirish.
x=210-3y-2z
Ikkala tarafdan 2z ni ayirish.
3y+5+2z=215-x
Ikkala tarafdan x ni ayirish.
3y+2z=215-x-5
Ikkala tarafdan 5 ni ayirish.
3y+2z=210-x
210 olish uchun 215 dan 5 ni ayirish.
3y=210-x-2z
Ikkala tarafdan 2z ni ayirish.
3y=210-2z-x
Tenglama standart shaklda.
\frac{3y}{3}=\frac{210-2z-x}{3}
Ikki tarafini 3 ga bo‘ling.
y=\frac{210-2z-x}{3}
3 ga bo'lish 3 ga ko'paytirishni bekor qiladi.
y=-\frac{x}{3}-\frac{2z}{3}+70
210-x-2z ni 3 ga bo'lish.
