根据方程1/6(1/x+2005)+1/2=3/2,你能用较简便的方法求出1/3(1/x+2005)+1/2(1/x+2004)+m=1中m的值吗?
急啊~~各位哥哥姐姐帮帮忙~~

1/6(1/x+2005)+1/2=3/2
1/6(1/x+2005)=1
1/x+2005=6
1/x+2004=5
1/3(1/x+2005)+1/2(1/x+2004)+m=1
1/3×6+1/2×5+m=1
2+2.5+m=1
m= -3.5
因为1/6(1/x+2005)+1/2=3/2
所以 (1/x+2005)=6
1/3(1/x+2005)+1/2(1/x+2004)+m=1
1/3x6+1/2x5+m=1
m=1-2-2.5
m=-3.5
1/x+2005=6
1/3(1/x+2005)+1/2(1/x+2004)+m=1/3(1/x+2005)+1/2(1/x+2005-1)+m
=2+5/2+m=1
m=-7/2
