Baham ko'rish
Klipbordga nusxa olish
3x+3z=-21+6y
6y ni ikki tarafga qo’shing.
3x=-21+6y-3z
Ikkala tarafdan 3z ni ayirish.
3x=6y-3z-21
Tenglama standart shaklda.
\frac{3x}{3}=\frac{6y-3z-21}{3}
Ikki tarafini 3 ga bo‘ling.
x=\frac{6y-3z-21}{3}
3 ga bo'lish 3 ga ko'paytirishni bekor qiladi.
x=2y-z-7
-21+6y-3z ni 3 ga bo'lish.
-6y+3z=-21-3x
Ikkala tarafdan 3x ni ayirish.
-6y=-21-3x-3z
Ikkala tarafdan 3z ni ayirish.
-6y=-3x-3z-21
Tenglama standart shaklda.
\frac{-6y}{-6}=\frac{-3x-3z-21}{-6}
Ikki tarafini -6 ga bo‘ling.
y=\frac{-3x-3z-21}{-6}
-6 ga bo'lish -6 ga ko'paytirishni bekor qiladi.
y=\frac{x+z+7}{2}
-21-3x-3z ni -6 ga bo'lish.
