(x+y)+(x+3)i=(3x+2y)+yi求实数x、y的值

(3x+2y)+(5x-y)i=17-2i.求x与y (2x+y)+(x-2y)i=3-i 求实数x,y天才帮帮忙 (x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)= (x+y)(x-y)+(x-y)平方-(x-y)(3x-y) 其中x=-2 y=3分之一 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y) (x+y)(2x-3y)=? x(x-y)2-(y-x)3 如果（x-y)+(2x-3)i=（3x+y)+(x+2y)i,求实数x,y的值 3、已知(x+y)+(x-2y)i=(2x-5)+(3x+y)i,求实数x,y的值. 急,速度好评 [2/3x-2/x+y(x+y/3x-x-y)]/x-y/x 化简：{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x 计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x 化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x (x+y)+(x+3)i=(3x+2y)+yi求实数x、y的值 如昊(x+y)+(X+3)i=(3x+2y)+yi求实数x,y的值急用 已知(x/1-i)+(y/1-2i)=5/1-3i求x+y 3^x+2x=y,x (2x-1)+i=y-(3-y)iy,y是纯虚数,x是实数,则x+y=?
