(x-1/2009)+(x-2/2008)=(x+3/2007)+(x+4/2006)
\(\dfrac{x-1}{2009}+\dfrac{x-2}{2008}=\dfrac{x-3}{2007}+\dfrac{x-4}{2006}\)
Tìm x biết : x - 1 / 2009 + x - 2 / 2008 = x - 3 / 2007 + x- 4 / 2006
a,x-1/2009+x-2/2008=x-3/2007+x-4/2006
b,x/4-1/y=3/4
Tìm x biết:
(x - 1)/2009 + (x - 2)/2008 = (x - 3)/2007 + (x - 4)/2006
Câu 1: So sánh các số hữu tỉ:
A = 2006/2007 - 2007/2008 + 2008/2009 - 2009/2010 với B = -1/2006 x 2007 - (-1)/2007 x 2008
(4-x).(2x+1/3)=(2006/2007-2007/2008+2008/2009).(2/3-1/4-5/12)
giúp mình nhé thank nhiều :D
tìm x,biết:\(\frac{x+1}{2009}+\frac{x+2}{2008}=\frac{x+3}{2007}+\frac{x+4}{2006}\)
