x+y+z=U
2.已知(x,y,z)=(1,0,-1)為ax+by+cz=0的一組解,(x,y,z)=(1,-1,0)不是
x+y+z=0
0
px+qy+rz=0
x+y+z=1
ax+by+cz=0的解,(x,y,z)=(2,3,4)為ax+by+cz=2的一組解,則下列哪
px+qy+rz= 0
x+y+z=1
些選項也是{ax+by+cz=2的解?
px+qy+rz=3
px+qy+rz=3
2a+3b-4C = 2
2p+39-42=3
(1)(x, y, z)=(3,-4,2) (2) (x,y,z)=(-4,2,3) (3)(x, y, z) = (3,3,-5)
(4)(x, y, z) = (1,3,-3) (5) (x, y, z) = (1,0,0).
