Find the equations for the line of intersctions of the planes:
I worked it out to be r(t)=3i-j-k+t(i-j)

Can you show your work, please?
solving for x we get
now solving for y we get
now solving forz we get
Hmm. There's something wrong with your method if x = t and x = 3 + t. That's impossible, isn't it? I would suggest row reducing your augmented matrix thus:
You should get a one-parameter family of solutions. What do you get?
Thanks I just realised that mistake!
So what do you get now?
Which is the published ans.
