x + 600 = 200 + 400
x + 600 = 600
x = 600 - 600
x = 0
X+600=200+400
X+600=600
X=600-600
X=0
Vậy X=0
x + 600 = 200 + 400
x + 600 = 600
x = 600 - 600
x = 0,0000
x + 600 = 200 + 400
x + 600 = 600
x = 600 - 600
x = 0
tk mk nha
x+600=200+400
x+600=600
x=600-600
x=0
nha, mik bạn rùi!
x + 600 = 200 + 400
x + 600 = 600
x = 600 - 600
x = 0
mik k ban ay roi k mik nha
