\frac{-2,3}{2} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.
-\frac{23}{20}x-y=7
\frac{-23}{20} kasri manfiy belgini olib tashlash bilan -\frac{23}{20} sifatida qayta yozilishi mumkin.
-\frac{23}{20}x=7+y
y ni ikki tarafga qo’shing.
-\frac{23}{20}x=y+7
Tenglama standart shaklda.
\frac{-\frac{23}{20}x}{-\frac{23}{20}}=\frac{y+7}{-\frac{23}{20}}
Tenglamaning ikki tarafini -\frac{23}{20} ga bo'lish, bu kasrni qaytarish orqali ikkala tarafga ko'paytirish bilan aynidir.
x=\frac{y+7}{-\frac{23}{20}}
-\frac{23}{20} ga bo'lish -\frac{23}{20} ga ko'paytirishni bekor qiladi.
x=\frac{-20y-140}{23}
7+y ni -\frac{23}{20} ga bo'lish 7+y ga k'paytirish -\frac{23}{20} ga qaytarish.

-y=7+\frac{23}{20}x
\frac{23}{20}x ni ikki tarafga qo’shing.
-y=\frac{23x}{20}+7
Tenglama standart shaklda.
\frac{-y}{-1}=\frac{\frac{23x}{20}+7}{-1}
Ikki tarafini -1 ga bo‘ling.
y=\frac{\frac{23x}{20}+7}{-1}
-1 ga bo'lish -1 ga ko'paytirishni bekor qiladi.
y=-\frac{23x}{20}-7
7+\frac{23x}{20} ni -1 ga bo'lish.
