Baham ko'rish
Klipbordga nusxa olish
10y+50xz=105
50 hosil qilish uchun 5 va 10 ni ko'paytirish.
50xz=105-10y
Ikkala tarafdan 10y ni ayirish.
50zx=105-10y
Tenglama standart shaklda.
\frac{50zx}{50z}=\frac{105-10y}{50z}
Ikki tarafini 50z ga bo‘ling.
x=\frac{105-10y}{50z}
50z ga bo'lish 50z ga ko'paytirishni bekor qiladi.
x=\frac{21-2y}{10z}
105-10y ni 50z ga bo'lish.
10y+50xz=105
50 hosil qilish uchun 5 va 10 ni ko'paytirish.
10y=105-50xz
Ikkala tarafdan 50xz ni ayirish.
\frac{10y}{10}=\frac{105-50xz}{10}
Ikki tarafini 10 ga bo‘ling.
y=\frac{105-50xz}{10}
10 ga bo'lish 10 ga ko'paytirishni bekor qiladi.
y=\frac{21}{2}-5xz
105-50xz ni 10 ga bo'lish.
