Tk mk nhá ???
Thanks !! ^^

100 + 200 +300 + 400 + 500 + 600 +700 + 800 + 900
=100 x ( 1 + 2 + 3 + 4 +5 + 6 + 7 + 8 + 9 )
=100 x 45
=4500



x + 100 = 200 - 700 - 100
x + 100 = - 500 - 100
x + 100 = - 600
x = - 600 - 100
x = - 700
x + 100 = 200 - 700 - 100
x + 100 = -600
x = -600 - 100
x = -700
400 + x = 700 - 20
400 + x = 500
x = 500 - 400
x = 100
=>400+x=500
=>x =500 - 400
=>x =100
