4y-9x=3-7z
Ikkala tarafdan 7z ni ayirish.
-9x=3-7z-4y
Ikkala tarafdan 4y ni ayirish.
\frac{-9x}{-9}=\frac{3-7z-4y}{-9}
Ikki tarafini -9 ga bo‘ling.
x=\frac{3-7z-4y}{-9}
-9 ga bo'lish -9 ga ko'paytirishni bekor qiladi.
x=\frac{4y}{9}+\frac{7z}{9}-\frac{1}{3}
3-7z-4y ni -9 ga bo'lish.
4y-9x=3-7z
Ikkala tarafdan 7z ni ayirish.
4y=3-7z+9x
9x ni ikki tarafga qo’shing.
4y=9x-7z+3
Tenglama standart shaklda.
\frac{4y}{4}=\frac{9x-7z+3}{4}
Ikki tarafini 4 ga bo‘ling.
y=\frac{9x-7z+3}{4}
4 ga bo'lish 4 ga ko'paytirishni bekor qiladi.
