已知2x-1+(y+1)i=x-y+(-x-y)i,求实数x,y的值

已知2x-1+(y+1)i=x-y+(-x-y)i,求实数x,y的值 已知(x/1-i)+(y/1-2i)=5/1-3i求x+y 已知Ix+y+1I+(x-y+3)^2=0,则(x+y)^2004等于 已知：（X-1）+（Y+2）i=2+3i ,其中X,Y∈R,求X,Y 已知x+y=a,2x-y=-2a,求[（x/y-y/x)/(x+y)-x(1/x-1/y)]/[(x+1)/y]的值 已知x,y为实数,i为虚数单位.若x/(1-i)+y/(1-2i)=5/(1-3i),则x+y的值为? 已知x,y∈R,i为虚数单位,且(x-2)i-y=-1+i则（1+i）^(x+y)=多少 关于高中虚数已知i是虚数单位,实数x、y满足(x+i)i+y=1+2i,则x-y的值 已知x为实数,y是纯虚数,且满足(2x-1)+(3-y)i=y-i,则x=____,y=____ 已知实数x 纯虚数y 满足(2x-1)+(3-y) i=y-i 求x y的值 已知(2x-1)+i=y-(3-y)i,其中x是纯虚数,y是实数,求x,y值RT 已知实数x,纯虚数y满足（2x-1)+(3-y) i=y-i.求x,y的值 已知x是实数,y是虚数,且满足(2x-1)+i=y-(3-y)i,求x和y 已知|x+y-1I+|x+1|=0 计算x-y-9的值 已知:【(x²+y²)-(x-y)²+2y(x-y)】/4y=1,求4x/4x²-y²-1/2x+y 已知：2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x) 已知x-y=1,求[(x+2y)^2+(2x+y)(x-4y)-3(x+y)(x-y)]除以y的值大神们帮帮忙 已知x-y=1,求[(x+2y)²+(2x+y)(x-4y)-3(x+y)(x-y)]÷y的值
