3x-\left(-2\right)-\left(-5x\right)=x+2
-2-5x teskarisini topish uchun har birining teskarisini toping.
3x+2-\left(-5x\right)=x+2
-2 ning teskarisi 2 ga teng.
3x+2+5x=x+2
-5x ning teskarisi 5x ga teng.
8x+2=x+2
8x ni olish uchun 3x va 5x ni birlashtirish.
8x+2-x=2
Ikkala tarafdan x ni ayirish.
7x+2=2
7x ni olish uchun 8x va -x ni birlashtirish.
7x=2-2
Ikkala tarafdan 2 ni ayirish.
7x=0
0 olish uchun 2 dan 2 ni ayirish.
x=0
Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. 7 0 ga teng bo‘lmasa, x 0 ga teng bo‘lishi kerak.
