Ta có: \(\frac{x+4}{2010}+\frac{x+3}{2011}=\frac{x+2}{2012}+\frac{x+1}{2013}\)
\(\Rightarrow\left(\frac{x+4}{2010}+1\right)+\left(\frac{x+3}{2011}+1\right)=\left(\frac{x+2}{2012}+1\right)+\left(\frac{x+1}{2013}+1\right)\)
\(\Rightarrow\left(x+2014\right)\left(\frac{1}{2010}+\frac{1}{2011}-\frac{1}{2012}-\frac{1}{2013}\right)=0\)
\(\Rightarrow x=-2014\)
Tìm x biết (x+4) /2010 + (x+3) / 2011 = (x+2) /2012 + (x+1) /2013
\(\dfrac{x+4}{2010}\)+\(\dfrac{x+3}{2011}\)=\(\dfrac{x+2}{2012}\)+\(\dfrac{x+1}{2013}\)
tìm x biết: x-1/2013 + x-2/2012 - x-3/2011= x-4/2010
x-1/2013+x-2/2012=x-3/2011+x-4/2010
Tìm x
Tìm x: \(\dfrac{x+4}{2010}+\dfrac{x+3}{2011}=\dfrac{x+2}{2012}+\dfrac{x+1}{2013}\)
x-1/2013+x-2/2012=x-3/2011+x-4/2010
a)2^x+2^x+1+2^x+2+2^x+3=480
b)(1/2+1/3+...+1/2012+1/2013)*x=2012/1+2011/2+2010/3+..+2/2011+1/2012
( x + 4 / 2010 + 1 ) + ( x + 3 / 2011 + 1 ) = ( x + 2 / 2012 + 1 ) + ( x + 1 / 2013 + 1 ) ! lm ơn giúp mik với
Tìm số hữu tỉ x biết:
a) \(\frac{x+4}{2009}+\frac{x+3}{2010}=\frac{x+2}{2011}+\frac{x+1}{2012}\)
b) \(\frac{x-2011}{2010}+\frac{x-2011}{2011}+\frac{x-2011}{2012}=\frac{x-2011}{2013}+\frac{x-2011}{2014}\)
