x + 960 = 1000 + 1000
x + 960 = 2000
x = 2000 - 960 = 11040
tk em nha phamthiminhtrang
x + 960 = 1000 + 1000
x + 960 = 2000
x = 2000 - 960
x = 1040
x+960=1000+1000
x+960=2000
x=2000-960
x=1040
x + 960 = 1000 + 1000
x + 960 = 2000
x = 2000 - 960
x = 1040.
X + 960 = 1000 + 1000
X + 960 = 2000
X =2000 - 960
X =1040
k cho mk nha
X + 960 = 1000 + 1000
X + 960 = 2000
