4x=28+7y
7y ni ikki tarafga qo’shing.
4x=7y+28
Tenglama standart shaklda.
\frac{4x}{4}=\frac{7y+28}{4}
Ikki tarafini 4 ga bo‘ling.
x=\frac{7y+28}{4}
4 ga bo'lish 4 ga ko'paytirishni bekor qiladi.
x=\frac{7y}{4}+7
28+7y ni 4 ga bo'lish.
-7y=28-4x
Ikkala tarafdan 4x ni ayirish.
\frac{-7y}{-7}=\frac{28-4x}{-7}
Ikki tarafini -7 ga bo‘ling.
y=\frac{28-4x}{-7}
-7 ga bo'lish -7 ga ko'paytirishni bekor qiladi.
y=\frac{4x}{7}-4
28-4x ni -7 ga bo'lish.
