若实数x,y满足x+y+(x-y)i=2,则xy的值等于

若实数x,y满足（1+i)x+(1-i)y=2,求x*y的值. 若实数x,y满足x+y+(x-y)i=2,则xy的值等于 若实数x,y满足x^2-xy-y^2 =0,则x/y=? 若实数x,y满足不等式组x>=0 ,y>=0,x+2y 若正实数x.y满足x+y=xy,则x+2y的最小值 已知实数x,y满足y=|x-1|若x+2y 若实数x,y满足y 若实数x,y满足不等式y 若实数x,y满足x²+y²-2x+4y=0,求x-y的最大值 若实数x y满足（x+y)²+（x+y)-2=0则x+y值为 若实数x,y满足x-y+1》=0,x+y>=0,x 若实数x,y满足x-y+1>=0,x+y>=0,x 设实数x,y满足 x>=0 x-2y>=0 x-y-2 设实数x,y满足约束条件：x>=2;y>=x;2x+y 已知实数x,y满足x-y 已知实数X,Y满足{|x+y| 实数x,y满足:｜x+y｜ 若实数x,y满足x
