38.5+24.08xy=12.04x^2; 38.5(4+x+y)+12.04xy^2=12.04(x/3+y)x^2,谁会解这个方程组,用软件也行.如matlab
先建立函数：
function q = myfun(p)
x=p(1);
y=p(2);
q(1)=38.5+24.08*x*y-12.04*x^2;
q(2)=38.5*(4+x+y)+12.04*x*y^2-12.04*(x/3+y)*x^2;
end
在运行一下命令：
x=fsolve('myfun',[0.5,0.5]',optimset('Display','off'))
得到的结果为：
x =
0.1868
-8.4647
即
x=0.1868,y=-8.4647
x 0.18682
y -8.4646

|x|/x+y/|y|+xy/|xy|=
化简:xy分之3x^2+2xy-xy分之2x^2-xy=
计算：( 根号xy-xy/x+根号xy)÷根号xy-y/x-y=
解方程组xy+x=16&xy-x=8
（-3x^y+2xy)-( )=4x^+xy
（xy-x的平方）*x-y分之xy=
(xy-x平方)乘以x-y份之xy=?
因式分解x^3+2xy-x-xy^2=
x³+2xy-x-xy²=（因式分解)
（x+1.8x)*75=1.8xy+1.2xy
(XY-X^2)除以X-Y/XY=?
证明|xy|=|x||y|
xy-(x+y)=1000
证明|xy|=|x||y|
sin(xy)=x 求dx/dysec(xy)-y ]/x 还是 x/[sec(xy)-y]
由已知x+y=-2,xy=3那么2(x+xy)-[(xy-3y)-x]-(-xy)等于多少?
(xy)/x
