若2/3x=5/6y,求x+y/y的值
若2/3x=5/6y,求x+y/y的值
若2/3x=5/6y,求x+y/y的值
2/3x=5/6y
所以x=5/4y
所以原式=(5/4y+y)/y=9/4
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
若x-y/x+y=5,求x-y/2x+2y+5x+5y/3x-3y的值
若x+y分之x-y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若2/3x=5/6y,求x+y/y的值
若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值
若x、y满足2x+y=6,x-3y=1,求7y(x-3y)²-2(3y-x)³的值
已知x-y=3,求[(x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
1、(-y^3)^5/y^3/ y^2+2(-y)^102、(x-y)^7/(y-x)^6+(x+y)^3/(x+y)^23、已知X^a=5,x^b=3,求X^(3a-2b)的值
x,y 满足x(x-2)-y(y-6)=-10,求x,y的值
y=3(x-y),x=2(x-y)求x,y的值
若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值
若|5x-2y-3|+(x+6y-11)X(x+6y-11)=0成立,求x,y的值,
当2x-y/x+y=3时,求代数式2x-y/2x+2y+x+y/6x-3y的值.
已知x.x+y.y-6x-8y+25=0,求3x.x+5y的值
已知x^3+xy^2+x+x^2y+y^3+y=0,求5x-6y/3x+4y的值.
若x,y∈R,(x+y)^2i+6i-x=-y+5(x+y)i-1,求x和y的值
已知x::y:z=3:4:5,(1)求x+y分之z的值;(2)若x+y+z=6,求x,y,z.
