最好有过程图也行
解
3/(x-2)-x/(2-x)=2
3/(x-2)+x/(x-2)=2
两边乘以x-2得：
3+x=2(x-2)
3+x=2x-4
2x-x=3+4
x=7
经检验x=7是方程的解
再问： �ɲ��������鷳��һ���⣬��ָ�л~
再答： �� ԭʽ =(x-3)/(x-1)(x+1)��(x+1)²/(x-3)-[1/(x-1)+1] =(x+1)/(x-1)-1/(x-1)-1 =(x+1-1)/(x-1)-1 =x/(x-1)-(x-1)/(x-1) =(x-x+1)/(x-1) =1/(x-1) =1/(-5/6-1) =1/(-11/6) =-6/11
