I got a different linear set of equations:
x = -5
y = -1/3
z = -20
Careful how your distributing.
Find x, y, z, if 2(x,-1,4)-3(-4,y,6)-0.5(4,-2,z)=(0,0,0)
Ok, I think I did this question correct, but the back of the says no.. I am guessing that the back of the book is wrong.. Can someone just verify? Thanks
2x-2+4=0
x=-3
12-3y-18=0
y=-2
-2+1-0.5z=0
z=2
is this ok?
