Bài 1 :Tìm x , biết .
(1+1/2+1/3+...+1/2013).x+2013=2014/1+2015/2+...+4026/2013
tim x ;
(1+1/2+1/3+...+1/2013).x+2013=2014/1+2015/2+...+4026/2013
tìm x biết (1+1/2+1/3+1/4+.........+1/2013)x+2013=2014/1+2015/2+2016/3+.........+4026/2013
giúp mik vs
nếu đầu bài sai thì sửa hộ mik luôn nha
\(\left(1+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2013}\right)x+2013=\frac{2014}{1}+\frac{2015}{2}+...+\frac{4025}{2012}+\frac{4026}{2013}\)
Tìm x, biết: (x+4)/2012+(x+3)/2013=(x+2)/2014+(x+1)/2015
Tìm x biết : (2-x)/2013=(1-x)/2014-x/2015
tìm x biết
((2-x)/2013)-1 = (1-x)/2014 - x/2015
tìm x biết (1/2 + 1/3 + 1/4 + .... + 1/2014 ) . x = 2013/1 + 2012/2 + ...+ 1/2013
Tìm x biết a |3-2x|=x+1
b (1/2+1/3+...+1/2014)×x=2013/1+2012/2+...+2/2012+1/2013
