(x+y-3)+(x-4)i=0 怎么算?求X,Y的值 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 请问算到4x/y=3y/x后怎么算出x,y, 二元一次方程(x+y)/2+(x-y)/3=6,4(x+y)-5(x-y)=2怎么算 x^2-4Y^2+X+3Y-1=0 2X-Y-1=0 怎么算 4x方y/(x-2y)(x+2y)怎么算[x方/x-2y]-4x方y/(x-2y)(x+2y)=? 求适合方程(x^2-4x-5)+(y^2+3y-4)i=0的实数x,y ｛（x,y）I x+y-3=0且x-y-1=0｝ (1+2i)(x+yi)=4+3i (x-2y)+(y+2x)i=4+3i c语言中x=(x=++y,x+5,x/5) x=3 y=4怎么算 matlab循环计算x=0:0.05:5.493;for i=1:110; f(x(i),y)=(3*5.493-x(i))*x(i)^2*(y-5.493)+2*5.493*(x(i)-y)*heaviside(x(i)-y);h(y)=-638.38+3265.159*y-1202.289*y^2+261*y^3-52.69*y^4+4.43*y^5;F(x(i))=int(f(x(i),y)*h(y),0,5.493);end程序提示Error using x+x+x+y+y=6.4 y+y+y+x+x=7.1 怎么算? (y-x)(x-y)^3(y-x)^5怎么算 y/(x+y)-x/(x-y)=?怎么算? 推倒公式:(x+y)(x*x-3x+y*y)=x*x*x+y*y*y怎么做. 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 （x+y-3)+(x-4)i=o求x与y x^2-4xy+3y^2=（x-3y)(x-y)x^2-4xy+3y^2 怎么分解成（x-3y)(x-y)
