2x+11+7x=7
7x ni ikki tarafga qo’shing.
9x+11=7
9x ni olish uchun 2x va 7x ni birlashtirish.
9x=7-11
Ikkala tarafdan 11 ni ayirish.
9x=-4
-4 olish uchun 7 dan 11 ni ayirish.
x=\frac{-4}{9}
Ikki tarafini 9 ga bo‘ling.
x=-\frac{4}{9}
\frac{-4}{9} kasri manfiy belgini olib tashlash bilan -\frac{4}{9} sifatida qayta yozilishi mumkin.
