2x=40+5x
Tenglamaning ikkala tarafini 5 ga ko'paytirish.
2x-5x=40
Ikkala tarafdan 5x ni ayirish.
-3x=40
-3x ni olish uchun 2x va -5x ni birlashtirish.
x=\frac{40}{-3}
Ikki tarafini -3 ga bo‘ling.
x=-\frac{40}{3}
\frac{40}{-3} kasri manfiy belgini olib tashlash bilan -\frac{40}{3} sifatida qayta yozilishi mumkin.
