5x-3y+2=0,则10^5x除10^3y=
5x-3y+2=0,则10^5x除10^3y=?
已知5X-3Y-2=0 求10的10X方除10的6Y方
若4x-3y=0则4x-5y除4x-5y的值为
1.已知:x-2y=3,求[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除4x 的值
先化简,再求值.其中x=-2,y=二分之一 {(x+y)2—(x+y)(x+3Y)—5Y平方}除2y
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuai
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
已知X,Y,满足(X+3Y)(X-3Y)=-10(Y^2-6/5)和2X(Y-1)+4(1/2X-1)=0
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
5(x+y)-2x=0 3x-10(x+y)=2
若【2x²-3y²-10y+5】²+根号x-2y,则x= y=
已知3x-y+5=0,求8的x次方除2的y次方的值
