156 - ( x - 2002) = 156
x - 2002 = 156 - 156
x - 2002 = 0
x = 2002 + 0
x = 2002
Đáp án : D
156 - ( x - 2002) = 156
x - 2002 = 156 - 156
x - 2002 = 0
x = 2002 + 0
x = 2002
Đáp án : D
Tìm x biết :

tìm x
a, x+1/10 + x+1/11 + x+1/12 = x+1/13 + x+1/14
b, x+4/2000 + x+3/2001 = x+2/2002 + x+1/2003
\(\frac{x+16}{2000}+\frac{x+15}{2001}=\frac{x+14}{2002}+\frac{x+13}{2003}\)
\(\frac{x}{2000}+\frac{x+1}{2001}+\frac{x+2}{2002}+\frac{x+3}{2003}=4\)
\(\frac{x-5}{2000}+\frac{x-4}{2001}+\frac{x-3}{2002}=\frac{x-2}{2003}+\frac{x-1}{2004}+\frac{x}{2005}\)
