(3x+2y)+(5x-y)i=17-2y求x和y要过程在线等谢谢
5x-y=0
y=5x
3x+3y=17-2y
3x+25x=17
x=17/28
y=85/28
5x-y=0,
y=5x
(3x+2y)=17-2y
(3x+10x)=17-10x
23x=17,
x=17/23,
y=85/23
(3x+2y)+(5x-y)i=17-2i.求x与y
求适合下列方程的实数x和y的值 1.(3x+2y)+(5x-y)i=17-2i 2.(x+y-3)+(x-4)i=(x+y-3)+(x-4)i=0
已知(x/1-i)+(y/1-2i)=5/1-3i求x+y
(2x+y)+(x-2y)i=3-i 求实数x,y天才帮帮忙
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
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
若x,y∈R,(x+y)^2i+6i-x=-y+5(x+y)i-1,求x和y的值
求适合下列条件的实数x和y的值:1、(3x+2y)+(5x-y)i=17-2i;2、(3x-4y)+(2y+3)i=0
(3x+2y)+(5x-y)i=17-2y求x和y要过程在线等谢谢
把(x-y)看作一个整体,化解:5(x-y)+2(x-y)-4(x-y)= 3(x-y)把(x-y)看作一个整体,化解:5(x-y)+2(x-y)-4(x-y)=3(x-y)²-4(x-y)+7(x-y)-6(x-y)²=
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5
求方程的实数x与y的值 (3x+2y)+(5x-y)i=17-2i
求方程实数x与y的值.(3x+2y)+(5x–y)i=17-2i
