若|x-2y+5|与(3x-y-5)2互为相反数,则x=______,y=_________若|x-2y+5|与(3x-y-5)2互为相反数,则x=______,y=_________若|x-2y+5
若|x-2y+5|与(3x-y-5)2互为相反数,则x=______ ,y=_________
若|x-2y+5|与(3x-y-5)2互为相反数,则x=______ ,y=_________
若|x-2y+5|与(3x-y-5)2互为相反数,则x=______ ,y=_________
若|x-2y+5|与(3x-y-5)2互为相反数,
则:|x-2y+5|+(3x-y-5)2=0
|x-2y+5|=0,(3x-y-5)2=0
x-2y+5=0,3x-y-5=0
则x=___3___ ,y=______4___
若|x-y-5|与|2x+3y-15|互为相反数,则x+y=?
若|x+2y-5|与(3x-y-1)的2次方互为相反数,则x+y=
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
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
已知|2-x|与|x-y+4|互为相反数,求代数式3(x-y)-5(x-y)*2-3(x-y)+(y-x)*2-4(x+y)+3(y-x)的值
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
若|x-y-5|与|2x+3y-15|互为相反数,则x+y=.若|x-1|+2(y+3)二次方=0,则x+y=.;|x|+|y|=.
