180-x-\left(-20\right)=x
x-20 teskarisini topish uchun har birining teskarisini toping.
180-x+20=x
-20 ning teskarisi 20 ga teng.
200-x=x
200 olish uchun 180 va 20'ni qo'shing.
200-x-x=0
Ikkala tarafdan x ni ayirish.
200-2x=0
-2x ni olish uchun -x va -x ni birlashtirish.
-2x=-200
Ikkala tarafdan 200 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-200}{-2}
Ikki tarafini -2 ga bo‘ling.
x=100
100 ni olish uchun -200 ni -2 ga bo‘ling.
