解方程：（x+3)(y-2)=(x-3)(y+10) (x-1)(y+3)=(x+2)(y+12)

解方程：（x+3)(y-2)=(x-3)(y+10) (x-1)(y+3)=(x+2)(y+12)
解方程：（x+3)(y-2)=(x-3)(y+10) (x-1)(y+3)=(x+2)(y+12)

解方程：（x+3)(y-2)=(x-3)(y+10) (x-1)(y+3)=(x+2)(y+12)
3y-2x-6=10x-3y-30
6y-12x+24=0
y-2x+4=0
3x-y-3=2y+12x+24
3y+9x+27=0
y+3x+9=0
x=-1,y=-6

（x+3)(y-2)=(x-3)(y+10) 化简后得出：y=2x-4
(x-1)(y+3)=(x+2)(y+12) 化简后得出： y-3x-9
由上边2个式子可得：
x=-1
y=-6
