若(3x+2y)^2+/2x+3y+5/=0,则x,y分别等于多少?
若(3x+2y)^2+/2x+3y+5/=0,则x,y分别等于多少?
若(3x+2y)^2+/2x+3y+5/=0,则x,y分别等于多少?
(3x+2y)^2+|2x+3y+5|=0
(3x+2y)^2=0
|2x+3y+5|=0
3x+2y=0
2x+3y+5=0
6x+4y=0
6x+9y=-15
9y-4y=-15
y=-3
x=-2/3y=2
(3x+2y)^2=0
/2x+3y+5/=0
所以x=2,y=-3
化简:5(x-y)+2(x+y)-3(x-y)
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(2x-3y)-(5x-y)
(2X-3y)-(5x-y)
(2x-5y)(3x+y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
x(x-y)2-(y-x)3
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
[(x+2y)(x-2y)-(2x-y)^2+(3x-y))2x-5y)]/(-x)我急用
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
[(x+2y)(x-2y)-(2x-y)²+(3x-y(2x-5y)]/(-x)的解答
若x-y/x+y=5,求x-y/2x+2y+5x+5y/3x-3y的值
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
