Tìm X
x-1/2000 + x-3/1998 + x-5/1996 + x/667 = 6
\(\frac{x-10}{1994}+\frac{x-8}{1996}+\frac{x-6}{1998}+\frac{x-4}{2000}+\frac{x-2}{2002}=\frac{x-2002}{2}+\frac{x-2000}{4}+\frac{x-1998}{6}+\frac{x-1996}{8}+\frac{x-1994}{10}\)
tìm x biết
a, x+1/2000+x+2/1999+x+3/1998=x+4/1997+x+5/1996+x+6/1995
b. (x+1)+(x+2)+..........+(x+200)=100
c, |2,5-x|=1,3
d, 7+2*|2x+1|=77
Tìm x, biết x+1/1999+x+2/1998+x+3/1997=x+4/1996+x+4/1995+x+6/1994
x-6/1998+x-4/2000=x-2000/4+x-1998/6
Tìm x :
a) \(\frac{x+1}{2000}+\frac{x+2}{1999}+\frac{x+ 3}{1998}+\frac{x+4}{1997}=-4\)
\(b.\frac{x+1}{1999}+\frac{x+2}{2000}+\frac{x+3}{2001}=\frac{x+4}{2002}+\frac{x+5}{2003}+\frac{x+6}{2004}\)
Tìm x biết:
1) \(\frac{x+1}{2}+\frac{x+1}{3}+\frac{x+1}{4}=\frac{x+1}{5}+\frac{x+1}{6}\)
2) \(\frac{x+1}{2009}+\frac{x+2}{2008}+\frac{x+3}{2007}=\frac{x+10}{2000}+\frac{x+11}{1999}+\frac{x+12}{1998}\)
tìm x biết:
\(\frac{x}{2000}+\frac{1}{500}+\frac{x}{2001}+\frac{1}{667}=\frac{x}{2002}+\frac{1}{1001}+\frac{x}{2003}+\frac{1}{2003}\)
x+1/2009+x+2/2008+x+3/2007=x+10/2000+x+11/1999+x+12/1998
