21x=7+14y
14y ni ikki tarafga qo’shing.
21x=14y+7
Tenglama standart shaklda.
\frac{21x}{21}=\frac{14y+7}{21}
Ikki tarafini 21 ga bo‘ling.
x=\frac{14y+7}{21}
21 ga bo'lish 21 ga ko'paytirishni bekor qiladi.
x=\frac{2y+1}{3}
7+14y ni 21 ga bo'lish.
-14y=7-21x
Ikkala tarafdan 21x ni ayirish.
\frac{-14y}{-14}=\frac{7-21x}{-14}
Ikki tarafini -14 ga bo‘ling.
y=\frac{7-21x}{-14}
-14 ga bo'lish -14 ga ko'paytirishni bekor qiladi.
y=\frac{3x-1}{2}
7-21x ni -14 ga bo'lish.
