(x+4)/2011+(x+3)/2012=(x+2)/2013+(x+1)/2014.tìm x
Tìm x biết (x+4) /2010 + (x+3) / 2011 = (x+2) /2012 + (x+1) /2013
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
\(\dfrac{x+4}{2010}\)+\(\dfrac{x+3}{2011}\)=\(\dfrac{x+2}{2012}\)+\(\dfrac{x+1}{2013}\)
tìm x biết: x-1/2013 + x-2/2012 - x-3/2011= x-4/2010
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
Tìm x : x+4/2010+ x+3/2011=x+2/2012+ x+1/2013
( x + 4 / 2010 + 1 ) + ( x + 3 / 2011 + 1 ) = ( x + 2 / 2012 + 1 ) + ( x + 1 / 2013 + 1 ) ! lm ơn giúp mik với
