|x-5|+|y-8|=0,则x=( ),y=( )|x-5|+|y-8|=0,则x=( ),y=( ) 速求
|x-5|+|y-8|=0,则x=( ),y=( )
|x-5|+|y-8|=0,则x=( ),y=( ) 速求
|x-5|+|y-8|=0,则x=( ),y=( )|x-5|+|y-8|=0,则x=( ),y=( ) 速求
绝对值均大于等于零
因此|x-5|=0,|y-8|=0
所以x-5=0,y-8=0
所以x=5,y=8
|x-5|+|y-8|=0
∵|x-5|≥0,|y-8|≥0
∴x-5=0,y-8=0
∴x=5,y=8

|x-5|+|y-8|=0,则x=( 5),y=( 8)
不懂可追问,有帮助请采纳,谢谢!
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是()?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8?(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
(5x-6y)(x+y)=0(x不等于y),则y/x=
若5X-8Y=0,则X+3Y/X-3Y=
已知5|x+y-3|+(x-y)²=0则x=,y=
已知|5x-y-8|+(7y-x+2)=0则4x+6y
x+5y+2=0,则4^2x+y*8^y-x
如果5x=9y(x,y都不等于0),则x:y=( )
(x-y-5)^2+|x+6y+2|=0,则x-y^2=
已知x*x+4x+y*y-2y+5=0,则x*x+y*y=?
(x+y-5)*(x+y-5)+(x-y+3)=0 x*x-y*y
已知:3x-5y=0,求x/y,x-y/y,x-y/x
先化简,再求值 [2/3x - 2/x+y(x+y/3x -x-y)]*x/x-y,其中5x+3y=0
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
|x-5|+|y-8|=0,则x=( ),y=( )|x-5|+|y-8|=0,则x=( ),y=( ) 速求
若实数x、y满足x平方+y平方-4x-2y+5=0,求根号8y-2x分之(根号x)+y
已知x.x+y.y-6x-8y+25=0,求3x.x+5y的值
若(X×X+Y×Y)(X×X+Y×Y-5)=36,则X×X+Y×Y=
