若2x+2y+3z+15=2√x+4√(2y-1)+6√(3z+2)求x,y,z.PS：√(3z+2)就是“根号3z+2”以此类推

若2x+2y+3z+15=2√x+4√(2y-1)+6√(3z+2)求x,y,z.PS：√(3z+2)就是“根号3z+2”以此类推 若实数XYZ满足2|x-y|+√2y+z+z方-z+1//4=0 求X+Y+Z 2y+z在根号里 x+2y=3x+2z=4y+z 求x:y:z 若x+y+z=3y=2z,则x/x+y+z=? 若x,y,z成等差数列,则(z-x)^2-4(x-y)(y-z)= x+y/2=z+x/3=y+z/4 x+y+z=27 2|X-Y|+√2Y+Z+Z²-Z+1/4=0求X+Y+Z的值 x+2y+3z=10,4x+3y+2z=15则x+y+z= x+2y+3Z=10,4x+3y+2z=15,求x+y+z= 2x+y+3z=10,3x+4y+2z=15,则x+y+z= 若x/2=y/3=z/4,则3x-2y+5z/x+y+z= 若x:y:z=2:3:4,求x+y+z/x-2y+3z的值 2x+3y-z=9,x+y+z=15,5x-4y-z=0 若x/3=y/4=z/5,求x+y+z/3x-2y+z的值. 若x/2=y/3=z/4不等于0,求x+y+z/x+y-z的值 若x/2=y/3=z/4,则x+y+z/x=多少? 若x,y,z成等差数列,则(z-x)^2-4(x-y)(y-x)= 2x+z=10 x+y-z=4 3x-y-z=0
