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