Ta có:
\(\frac{x+4}{2008}+1+\frac{x+3}{2009}+1=\frac{x+2}{2010}+1+\frac{x+1}{2011}+1\)
\(\frac{x+2012}{2008}+\frac{x+2012}{2009}=\frac{x+2012}{2010}+\frac{x+2012}{2011}\)
\(\left(x+2012\right)\left(\frac{1}{2008}+\frac{1}{2009}-\frac{1}{2010}-\frac{1}{2011}\right)=0\)
\(x=-2012\)
Tìm x biết (x-1)/2011+(x-2)/2010-(x-3)/2009=(x-4)/2008
Tìm x∈Z biết
\(\dfrac{x+4}{2008}+\dfrac{x+3}{2007}=\dfrac{x+2}{2009}+\dfrac{x+1}{2010}\)
Tìm x,biết
x+4/2007 + x+3/2008 = x+2/2009 + x+1/2010
tìm x biết :
a)(x+4) / 2010 + (x+3)/2011 =( x+2)/2012 + (x+1)/2013
b) (x-1)/2010 + (x-2)/2009 = (x-3)/2008 + (x-4)/2007
tìm x để đa thức sau nhận giá trị dương: x^2 + 2017x
\(\frac{x-1}{2011}+\frac{x-2}{2010}-\frac{x-3}{2009}=\frac{x-4}{2008}\)tìm x
tìm x biết:
\(\frac{x-1}{2011}+\frac{x-2}{2010}+\frac{x-3}{2009}=\frac{x-4}{2008}\)
Tìm x biết:
a) x+2x+3x+4x+......+2011x=2012.2013
b)(x-1)/2011+(x-2)/2010-(x-3)/2009=(x-4)/2008
tìm x:
x+3/2007-x+3/2008=x+3/2010-x+3/2009
giải giúp mình nha
Tìm x : \(\frac{x+4}{2007}+\frac{x+3}{2008}=\frac{x+2}{2009}+\frac{x+1}{2010}\)
