诺x,y满足x+3y+｜3x-y｜=19,2x+y=6,则x是多少,y是多少?

变量x,y满足约束条件,x+y>=3,x-y>=-1,2x-y 诺x,y满足x+3y+｜3x-y｜=19,2x+y=6,则x是多少,y是多少? 若x,y为正整数,且满足3x(x+y)-y(x+y)=7,求x,y 设x.y满足条件y>=0.X-Y+1>=0.x+y-3 已知实数x,y满足约束条件x+y>3,y 若变量x,y满足约束条件{x>=-1;y>=x;3x+2y 设x,y满足约束条件{x>=0,y>=x,4x+3y 设x,y满足约束条件x>=0 y>=x 4x+3y 满足3x+4y 设自然数x,y满足x小于y,x^3+19y=y^3+19x,则x+y等于? 设x,y满足x＋3y＋|3x－y|＝19,2x＋y＝6则X= Y= 设变量x,y满足约束条件x-y>-1,x+y>1,3x-y 已知实数x.y满足根号(x+y-8)+根号(8-x-y)=根号(3x-y-4)+根号(x-2y+7),求x,y 实数x,y满足x^3-y^3-3xy=1,则x-y= 设变量X,Y满足约束条件{X-Y+3>=0,X+Y>=0,-2 设变量x,y满足约束条件:x-y+3>=0 x+y>=0 -2 若x,y 满足条件{x>=1 y>=1 x+y-3 实数x.y满足(x-2(平方)+y(平方)=3则y/x的最大值?
