2x=18+7y
7y ni ikki tarafga qo’shing.
2x=7y+18
Tenglama standart shaklda.
\frac{2x}{2}=\frac{7y+18}{2}
Ikki tarafini 2 ga bo‘ling.
x=\frac{7y+18}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
x=\frac{7y}{2}+9
18+7y ni 2 ga bo'lish.
-7y=18-2x
Ikkala tarafdan 2x ni ayirish.
\frac{-7y}{-7}=\frac{18-2x}{-7}
Ikki tarafini -7 ga bo‘ling.
y=\frac{18-2x}{-7}
-7 ga bo'lish -7 ga ko'paytirishni bekor qiladi.
y=\frac{2x-18}{7}
18-2x ni -7 ga bo'lish.
