解方程组:(x+2)²-1=(x+3)(x-3)-4y(x-1)(y+6)=(x+2)(y+4)解方程组:(x+2)²-1=(x+3)(x-3)-4y(x-1)(y+6)=(x+2

解方程组:(x+2)²-1=(x+3)(x-3)-4y (x-1)(y+6)=(x+2)(y+4)
解方程组:(x+2)²-1=(x+3)(x-3)-4y (x-1)(y+6)=(x+2)(y+4)

解方程组:(x+2)²-1=(x+3)(x-3)-4y (x-1)(y+6)=(x+2)(y+4)
(x+2)²-1=(x+3)(x-3)-4y
(x-1)(y+6)=(x+2)(y+4)
4X+3=-9--4y
X=-3-y代入
(-3-y-1)(y+6)=(-3-y+2)(y+4)
(y+4)(y+6)=(y+4)(y+1)
y=-4
X=1
