2x - 2011 = 2017
2x = 2017 + 2011
2x = 4028
x = 2014
Năm mới chúc vui vẻ
2x -2011 = 2017

Vậy :x = 2014
Happy new year!
2x-2011=2017
\(\Leftrightarrow2x=2017+2011=4028\)
\(\Leftrightarrow x=2014\)
2x - 2011 = 2017
2x = 2017 + 2011
2x = 4028
x = 4028 : 2
x = 2014
2x - 2011 = 2017
2x = 2017 + 2011
2x = 4028
x = 4028 : 2
x = 2014
2x-2011=2017
2x =2017+2011
2x =4028
X=4028÷ 2
X=2014
