2x-y=19-5
Ikkala tarafdan 5 ni ayirish.
2x-y=14
14 olish uchun 19 dan 5 ni ayirish.
2x=14+y
y ni ikki tarafga qo’shing.
2x=y+14
Tenglama standart shaklda.
\frac{2x}{2}=\frac{y+14}{2}
Ikki tarafini 2 ga bo‘ling.
x=\frac{y+14}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
x=\frac{y}{2}+7
14+y ni 2 ga bo'lish.
5-y=19-2x
Ikkala tarafdan 2x ni ayirish.
-y=19-2x-5
Ikkala tarafdan 5 ni ayirish.
-y=14-2x
14 olish uchun 19 dan 5 ni ayirish.
\frac{-y}{-1}=\frac{14-2x}{-1}
Ikki tarafini -1 ga bo‘ling.
y=\frac{14-2x}{-1}
-1 ga bo'lish -1 ga ko'paytirishni bekor qiladi.
y=2x-14
14-2x ni -1 ga bo'lish.
