依题意得:m^2-1/9=0
m^2=1/9
m=1/3,x=1或m=-1/3,x=-1
所以:3(X减m+y)减y(2m减3)=m(x减y)
1.m=1/3,x=1时:
3(x-1/3+y)-y(2/3-3)=1/3(x-y)
3(1-1/3+y)-y(-1/3)=1/3(1-y)
2+3y+(1/3)y=1/3-(1/3)y
(11/3)y=-5/3
y=-5/11
2.m=-1/3,x=-1时:
3(x+1/3+y)-y(-2/3-3)=-1/3(x-y)
3(-1+1/3+y)+(11/3)y=-1/3(-1-y)
3y+(11/3)y-2=-1/3+(1/3)y
(19/3)y=5/3
y=5/19
