x+200=300+500:5

x + 200 = 300 + 100

x + 200 = 400

        x = 400 - 200

         x = 200 

x+200=300+500:5

x+200=300+100

x+200=400

x=400-200

x=200

t tôi nhé

x + 200=300 + 500 : 5

x + 200 = 300+ 100

x + 200 = 400

x = 400 - 200

x = 200

x + 200 = 500 + 200 

x + 200 = 700

       x = 700 - 200

       x = 500

Thử lại : 500 + 200 = 700 

               500 + 200 = 700

Vậy 700 = 700
