3x-8=12+4y
4y ni ikki tarafga qo’shing.
3x=12+4y+8
8 ni ikki tarafga qo’shing.
3x=20+4y
20 olish uchun 12 va 8'ni qo'shing.
3x=4y+20
Tenglama standart shaklda.
\frac{3x}{3}=\frac{4y+20}{3}
Ikki tarafini 3 ga bo‘ling.
x=\frac{4y+20}{3}
3 ga bo'lish 3 ga ko'paytirishni bekor qiladi.
-4y-8=12-3x
Ikkala tarafdan 3x ni ayirish.
-4y=12-3x+8
8 ni ikki tarafga qo’shing.
-4y=20-3x
20 olish uchun 12 va 8'ni qo'shing.
\frac{-4y}{-4}=\frac{20-3x}{-4}
Ikki tarafini -4 ga bo‘ling.
y=\frac{20-3x}{-4}
-4 ga bo'lish -4 ga ko'paytirishni bekor qiladi.
y=\frac{3x}{4}-5
20-3x ni -4 ga bo'lish.
