100x+2z=19-5y
Ikkala tarafdan 5y ni ayirish.
100x=19-5y-2z
Ikkala tarafdan 2z ni ayirish.
100x=19-2z-5y
Tenglama standart shaklda.
\frac{100x}{100}=\frac{19-2z-5y}{100}
Ikki tarafini 100 ga bo‘ling.
x=\frac{19-2z-5y}{100}
100 ga bo'lish 100 ga ko'paytirishni bekor qiladi.
x=-\frac{y}{20}-\frac{z}{50}+\frac{19}{100}
