你的意思是x,y,z为整数吧?
x=1 y=9 z=90
解方程组:X+Y+Z=100,10X+5Y+0.5Z=100
x+y+z=15 x+5y+10z=70 x,y,z,各是几?
x+y+z=15 x+5y+10z=70 x,y,z,各是几?
X+Y-Z=15 X+5Y+10Z=70 求:X、Y、Z
5x+1.5y+0.5z=100 x+y+z=100 求 X Y Z
请高手帮我解几道3元1次的方程组!好的100分,x+2y+3z=15x-y+7z=20x+3y+2z=14x+y-z=3y+z-x=5z+x-y=7x+y-z=0.5x-3y+2z=03x+2y-z=23x-2y=12y+3z=2x+5z=315x-3y+2z=13x+4y-z=-18z=136x-y-z=32x-4y+8z=53x-6y-z=10x+y=3y+z=5x+z=6
(4x-2y-z)-{5x-[8y-2z-(x-2y)]-x-(3y-10z)}=?
X+Y+Z=15 X+5Y+10Z=70,Y.Z的值
解方程 Y=X+Z Y-Z=2 100Z+10Y+X-(100X+10Y+Z)=99 Y=X+ZY-Z=2100Z+10Y+X-(100X+10Y+Z)=99
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian
6x+5y+3z=100 x+y+z=30 求 x y
0.5x+3y+5z=100 x+y+z=100
(4x-2y-z)-{5x-[8y-2z-(x+y)]-2(3y-10z)}=?好难啊
(x+y-z)(x-y+z)=
100x+10y+z=27(x+y+z) x+z=y+1 100z+10y+x-100x-10y-z=99 解方程组100x+10y+z=27(x+y+z) x+z=y+1 100z+10y+x-100x-10y-z=99 .急.
