\(\left(\frac{1}{2}+\frac{1}{3}+....+\frac{1}{2014}+\frac{1}{2015}\right).x=\frac{2014}{1}+\frac{2013}{2}+\frac{2012}{3}+...+\frac{2}{2013}+\frac{1}{2014}\)
Tìm x
a, x+1/2 + x+2/3 + x+3/4 + x+4/5 + ....+ x+5/6=5
b, x+1/2017 + x+2/2016 + x+3/2015 = x+4/2014 + x+5/2013 + x+6/2012
Tìm x biết: \(\frac{x+1}{2015}+\frac{x+2}{2014}+\frac{x+3}{2013}+\frac{x+4}{2012}\) = -4
Tìm x biết:
