解方程:x-2010/97+x-1/2009+3-x/2007=0
答
x-2010/97+x-1/2009+3-x/2007=0
x+x-x/2007=2010/97+1/2009-3
4013x/2007=(2010*2009+97-3*97*2009)/97*2009
4013x/2007=3453568/194873
x=3453568/194873*2007/4013
=6931310976/782025349
答
(x-2010)/97=(x-3)/2007-(x-1)/2009
(x-2010)/97=(2009x-6027-2007x+2007)/2007*2009
(x-2010)/97=(2x-4020)/2007*2009
(x-2010)/97-2(x-2010)/2007*2009=0
(x-2010))1/97-2/2007*2009)=0
x-2010=0
x=2010
