5x-y=18-8z
Ikkala tarafdan 8z ni ayirish.
5x=18-8z+y
y ni ikki tarafga qo’shing.
5x=y-8z+18
Tenglama standart shaklda.
\frac{5x}{5}=\frac{y-8z+18}{5}
Ikki tarafini 5 ga bo‘ling.
x=\frac{y-8z+18}{5}
5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.
8z-y=18-5x
Ikkala tarafdan 5x ni ayirish.
-y=18-5x-8z
Ikkala tarafdan 8z ni ayirish.
-y=18-8z-5x
Tenglama standart shaklda.
\frac{-y}{-1}=\frac{18-8z-5x}{-1}
Ikki tarafini -1 ga bo‘ling.
y=\frac{18-8z-5x}{-1}
-1 ga bo'lish -1 ga ko'paytirishni bekor qiladi.
y=5x+8z-18
18-5x-8z ni -1 ga bo'lish.
