Find the parametric equations for the line of intersection of the planes x+y+z=3 and x-y+2z=2

I took the cross product of the 2 equations and got 3i-j-2k

I then set z=0 and got x=5/2 and y=1/2.

I got:

x=5/2 +3t

y=1/2-t

z=-2t

However, the answers are supposed to be:

x=5/2-(3/2)t

y=1/2+(1/2)t

z=t
