600+x=500+500

600+x=1000

       x=1000-600

      x=400

tk cho mk nha

600 + x = 500 + 500

600 + x = 1000

          x = 1000 - 600

           x = 400

x + 500 = 600 + 500

=> x +500 = 1100

=> x= 1100- 500

=> x = 600

x + 500 = 600 + 500

x + 500 = 1100

x           = 1100 - 500

x            = 600

x + 600 = 500 + 500

x + 600 = 1000

x          = 1000 - 600

x          = 400

x+600=1000

x         =1000-600

x        =400

k cho mik với

x + 600 = 500 + 500

x+600=1000

x=1000-600

x=400

=400 nha ban 

 k minh nha

x + 600 = 1000

x          = 1000 - 600

x          = 400

x + 600 = 1000

x = 1000  - 600

x = 400
