若x,y满足|x-5|+|y-2|=0,则5x+2y=b+1中b的值是多少?

变量x,y满足x-2y=0,x 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 若实数X,Y满足x²+y²-4x-2y+5=0求√x+y/√8y-2x 若实数x、y满足x*x+y*y-2x+4y+5=0,求x-y的值 若实数x,y满足不等式组x>=0 ,y>=0,x+2y 若实数x,y满足x^2-xy-y^2 =0,则x/y=? 若x.y满足条件2x+y-12=0,x-4y+10 若正整数X,Y满足2X+Y--XY=0,求X+Y的最小值 设Z=X+Y,其中X,Y满足X+2Y>=0,X-Y .先化简再求值：（2x+y）（2x+y)-(2x-y)平方其中X,Y满足X平方+Y平方-2X+4Y+5=0 若x,y满足|2x-y-3|+|3x+2y+1|=0,则x= y= 若x,y满足|x-y+1|+(x+y+3)^2=0则x^2-y^2= 若x y满足x^2+y^2-2x+4y=0求x-2y的最大值 设X,Y满足条件x-y+2>=0,x+y-4>=0,2x-y-5 若线段x ,y 满足[2x-3y]*[3x+2y]=0 则x/y=? 实数x,y满足2x+5y>=0,2x-3y>=-6,2x+y 若实数x,y满足x²+y²-2x+4y=0,求x-y的最大值 若实数x y满足（x+y)²+（x+y)-2=0则x+y值为
