解方程组:x+2y+3z=62x+3y+z=63x+y+2z=6
解方程组:x+2y+3z=62x+3y+z=63x+y+2z=6
解方程组2x+3y+z=6x−y+2z=−1x+2y−z=5
解方程组(1)x+y−z=6x−3y+2z=13x+2y−z=4
解方程组{3x+y-z=4,2x-y+3z=12,x+y+z=6}
解方程组:x+y+z=4,x+y+2z=5,3x+y-z=6
解方程组x:y=1:5y:z=2:3x+y+z=27.
解方程组:2X=3Y Y=2Z X+2Y+Z=16
解方程组2x+y-3z=1,x-2y+z=6,3x-y+2z=9求x,y,z的值
x=y/z=z/3,x+y+z =12,求2x+3y+4z是多少,
解方程组:3x+2y+5z=2x−2y−z=64x+2y−7z=30.
解方程组:3x−y+2z=32x+y−3z=11x+y+z=12
解方程组:5x−4y+4z=132x+7y−3z=193x+2y−z=18
